Assertion & Reason Test: The p-Block Elements - Question 1
Save

Directions: In the following questions, A statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as.

Assertion (A): N2 is less reactive than P4. 
Reason (R): Nitrogen has more electron gain enthalpy than phosphorus.

Detailed Solution for Assertion & Reason Test: The p-Block Elements - Question 1

Due to high bond dissociation energy of triple bond between the two N atoms, nitrogen (N) is less reactive than P4 and its electron gain enthalpy is less than phosphorus.

Assertion & Reason Test: The p-Block Elements - Question 2
Save

Directions: In the following questions, A statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as.

Assertion (A): Bismuth forms only one well characterised compound in +5 oxidation state.
Reason (R): Elements of group-15 form compounds in +5 oxidation state.

Detailed Solution for Assertion & Reason Test: The p-Block Elements - Question 2

Elements of group-15 form compounds in +5 oxidation state. Bismuth forms only one well characterised compound in +5 oxidation state which is BiF5. Due to inert pair effect bismuth exhibit +3 oxidation state and only forms trihalides. But due to small size and high electronegativity of fluorine, Bismuth forms BiF5.

Assertion & Reason Test: The p-Block Elements - Question 3
Save

Directions: In the following questions, A statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as.

Assertion (A): Both rhombic and monoclinic sulphur exist as S8 but oxygen exists as O2.
Reason (R): Oxygen forms pp-pp multiple bond due to small size and small bond length but pπ-pπ bonding is not possible in sulphur.

Detailed Solution for Assertion & Reason Test: The p-Block Elements - Question 3

Sulphur (S) exists as S8 but oxygen forms pπ-pπ multiple bonds which is not present in S.

Assertion & Reason Test: The p-Block Elements - Question 4
Save

Directions: In the following questions, A statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as.

Assertion (A): SF6 cannot be hydrolysed but SF4 can be.
Reason (R): Six atoms in SF6 prevent the attack of H2O on sulphur atom of SF6.
Detailed Solution for Assertion & Reason Test: The p-Block Elements - Question 4

SF6 is sterically protected due to presence of six F atoms around S atom which prevents the attack of H2O on SF6.

Assertion & Reason Test: The p-Block Elements - Question 5
Save

Directions: In the following questions, A statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as.

Assertion (A): HI cannot be prepared by the reaction of KI with concentrated H2SO4.
Reason (R): HI has lowest H–X bond strength among halogen acids.
Detailed Solution for Assertion & Reason Test: The p-Block Elements - Question 5

Both statements are correct but are independent of each other. HI cannot be prepared by the reaction of KI with concentrated H2SO4 as it results in the formation of HI which further oxidizes to I2 as H2SO4 is a strong oxidizing agent.

Assertion & Reason Test: The p-Block Elements - Question 6
Save

Directions: In the following questions, A statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as.

Assertion (A): F2 has lower bond dissociation energy than Cl2.
Reason (R): Fluorine is more electronegative than chlorine.
Detailed Solution for Assertion & Reason Test: The p-Block Elements - Question 6

F2 has higher bond dissociation enthalpy than Cl2.

Assertion & Reason Test: The p-Block Elements - Question 7
Save

Directions: In the following questions, A statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as.

Assertion(A): Group 18 gases exhibit very high ionisation enthalpy.
Reason (R): They have a stable electronic configuration.
Detailed Solution for Assertion & Reason Test: The p-Block Elements - Question 7

Group 18 gases exhibit very high ionisation enthalpy because they have a stable electronic configuration.

Assertion & Reason Test: The p-Block Elements - Question 8
Save

Directions: In the following questions, A statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as.

Assertion(A): Helium diffuses through most commonly used laboratory materials.
Reason(R): This gas has a very low melting  point.
Detailed Solution for Assertion & Reason Test: The p-Block Elements - Question 8

Helium diffuses through most commonly used laboratory materials which is an unusual property of this gas.

Assertion & Reason Test: The p-Block Elements - Question 9
Save

Directions: In the following questions, A statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as.

Assertion (A): HNO3 makes iron passive.
Reason (R): HNO3 forms a protective layer of ferric nitrate on the surface of iron.
Detailed Solution for Assertion & Reason Test: The p-Block Elements - Question 9

HNO3 makes iron passive and its passivity is attained by formation of a thin film of oxide on iron.

Assertion & Reason Test: The p-Block Elements - Question 10
Save

Directions: In the following questions, A statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as.

Assertion (A): NaCl reacts with concentrated H2SO4 to give colourless fumes with pungent smell. But on adding MnO2 the fumes become greenish yellow. 
Reason (R): MnO2 oxidises HCl to chlorine gas which is greenish yellow.
Detailed Solution for Assertion & Reason Test: The p-Block Elements - Question 10

Colourless fumes of hydrochloric acid (HCl) become greenish yellow because MnO2 oxidises HCl to chlorine gas.

Assertion & Reason Test: The p-Block Elements - Question 11
Save

Directions: In the following questions, A statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as.

Assertion (A): NaCl reacts with concentrated H2SO4 to give colourless fumes with pungent smell. But on adding MnO2 the fumes become greenish yellow.
Reason (R): MnO2 oxidises HCl to chlorine gas which is greenish yellow
Detailed Solution for Assertion & Reason Test: The p-Block Elements - Question 11

Colourless fumes of hydrochloric acid(HCl) because greenish yellow because MnO2 oxidises HCl to chlorine gas.

Assertion & Reason Test: The p-Block Elements - Question 12
Save

Directions: In the following questions, A statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as.

Assertion (A): H2O a liquid and H2S a gas.
Reason (R): Water molecules are held by H-bonds while in H2S molecules no such interactions are present between molecules.
Detailed Solution for Assertion & Reason Test: The p-Block Elements - Question 12

Due to small size and high electronegativity of oxygen, water is highly associated with intermolecular hydrogen bonding but molecules of H2S are held together by van der Waal’s forces of attraction. Hence, H2O is a liquid and H2S is a gas.

Assertion & Reason Test: The p-Block Elements - Question 13
Save

Directions: In the following questions, A statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as.

Assertion (A): F2 is a strong oxidizing agent.
Reason (R): Electron gain enthalpy of fluorine is less negative.
Detailed Solution for Assertion & Reason Test: The p-Block Elements - Question 13

Fluorine is the best oxidising agent because it has more reduction potential (more ability to lose the electrons) which is attributed to its high electronegativity.

Assertion & Reason Test: The p-Block Elements - Question 14
Save

Directions: In the following questions, A statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as.

Assertion (A): F2 has lower reactivity.
Reason (R): F-F bond has low Δbond Ho.
Detailed Solution for Assertion & Reason Test: The p-Block Elements - Question 14

Fluorine is the maximum reactive because of low bond dissociation enthalpy.

Assertion & Reason Test: The p-Block Elements - Question 15
