Test: Introduction to p-Block Elements - Question 1

The exhibition of the highest coordination number depends on the availability of vacant orbitals in the central atom. Which of the following elements is not likely to act as a central atom in MF3-6?

Detailed Solution for Test: Introduction to p-Block Elements - Question 1

The element M in the complex ion MF63-  has a coordination number of six. Since B has only s- and p-orbitals and no d – orbitals, therefore, at the maximum it can show a coordination number of 4. Thus, B cannot form a complex of the type MF63-.

Test: Introduction to p-Block Elements - Question 2

The order of ionization enthalpy for B, Al and Ga is:

Detailed Solution for Test: Introduction to p-Block Elements - Question 2

B > Al < Ga  The trend in ionization enthalpy is because there is decrease in Ionisation enthalpy from B to Al due to increase in size and from Al to Ga. Ga has more ionisation energy than Al due to uneffective screening effect.

Test: Introduction to p-Block Elements - Question 3

Which of the following p-block element can replace Cu for electric purpose?

Detailed Solution for Test: Introduction to p-Block Elements - Question 3

Al because  in reactivity series it is above Cu and hence it can displace it in electrolysis.

Test: Introduction to p-Block Elements - Question 4

Which of the following group 13 elements oxide is acidic in nature?​

Detailed Solution for Test: Introduction to p-Block Elements - Question 4

The acidic character of oxides of group 13 decreases down the group because the non-metallic character of elements decreases down the group and the metallic character increases.​
And we know that oxides of metals are basic in nature and oxides of non-metals are acidic in nature.

Thus, the acidic character of oxides of group 13 decreases down the group.
Example:

  • Boron (1st element of group 13) is non-metal, so its oxide is acidic.
  • Aluminum (2nd element of group 13) shows characteristics of both metal and non-metal, so its oxide shows amphoteric nature.
  • As we go down the group, indium and thalium (4th and 5th element of group 13) show metallic properties, so their oxides are basic.
Test: Introduction to p-Block Elements - Question 5

Which of the following elements exist as liquid in summer among group 13 elements?

Detailed Solution for Test: Introduction to p-Block Elements - Question 5

Galium can occur in liquid state if the room is above 29.76C which is its melting point. So,option d is correct

Test: Introduction to p-Block Elements - Question 6

Which of the following statements is true?

Detailed Solution for Test: Introduction to p-Block Elements - Question 6

The atomic radius of the Ga is less than Al because of poor screening effect. The atomic radius of Ga is slightly lesser than of Al because in going from Al to Ga, the electrons have already occupied 3d sub shell in Ga

Test: Introduction to p-Block Elements - Question 7

Which of the following is not an element of group 13?

Detailed Solution for Test: Introduction to p-Block Elements - Question 7

Group-13 Elements. Group-13 elements belong to the first group of p-block elements and include Boron (B), Aluminium (Al), Gallium (Ga), Indium (In) and Thallium (Tl). Boron is the only metalloid in the group while the rest of the elements are metals. Gallium is liquid at temperatures over 30oC.

Test: Introduction to p-Block Elements - Question 8

Which of the following statements regarding ozone is not correct?

Detailed Solution for Test: Introduction to p-Block Elements - Question 8

 The oxygen-oxygen bond length in ozone is identical with of molecular oxygen
The bond length in ozone is intermediate between those of single O-O and double O=O bonds.The bond angle is O3 is 117∘ with O-O distance 127.8pm.
 

Test: Introduction to p-Block Elements - Question 9

The maximum oxidation state shown by a p-block element is equal to the:

Detailed Solution for Test: Introduction to p-Block Elements - Question 9
  • The oxidation state of an element is related to the number of electrons that an atom loses, gains, or appears to use when joining with another atom in compounds. 
  • It also determines the ability of an atom to oxidize (to lose electrons) or to reduce (to gain electrons) other atoms or species.
  • They should release the total valence electrons to attain stability, so the maximum possible oxidation state is the number of valence electrons.
Test: Introduction to p-Block Elements - Question 10

Which of the following is the hardest element among group 13 elements?

Detailed Solution for Test: Introduction to p-Block Elements - Question 10

From top to bottom in a group size of a element increase as a result interatomic strength decrease from top to bottom.Due to this factor Boron is hardest element of group 13.
