Discussed Questions
Sravya Mehta upvoted   •  3 weeks ago

Which of the following compounds cannot give E1CB reaction?
  • a)
    CF3 – CHCl2
  • b)
    C6h5 – CH2 – CH2F
  • c)
    CH3 – CH2 – CH2Br
  • d)
Correct answer is option 'D'. Can you explain this answer?

Asf Institute answered

Compound d will give E2 reaction, Br is a better leaving group so formation of carboanion and removal of leaving group occurs simultaneously. But E1CB reaction is shown by poor leaving group like in compounds a, b and c.

Choose the correct answer from the following four choices.
Statement: Pyridine is more basic than pyrrole.
Reason: The nitrogen in pyrrole carries a proton while the nitrogen in pyridine does not.
Assertion: Nitrogen in trigonal geometry are generally more basic than nitrogens in a tetrahedral geometry. 
a)Both Reason and Assertion are correct.
b)Both Reason and Assertion are wrong.
c)Reason is correct and Assertion is wrong.
d)Reason is wrong and Assertion is correct.
The correct answer is option 'B'. Can you explain this answer?

Asf Institute answered
  • Pyridine is more basic than pyrrole because lone pair of electrons on N in pyridine and pyrrole are different in nature. These form a part of aromatic sextet in pyrrole, while not in pyridine.
  • Pyrrole, C4H4NH (in which N contributes a lone pair) has a pKa−3.8 but pyridine (where N is part of the ring's double bond)... more
  • In pyrrole, the lone pair electrons of the nitrogen atom gets involved with the 2 carbon-carbon double bonds in the 5-member ring to form a conjugated system of pi electrons, leading to greater stability of the molecule.
  • Pyridine, on the other hand, already has a stable conjugated system of 3 double bonds in the aromatic hexagonal ring, like benzene. Hence, the lone pair electrons on the N atom in pyridine can be easily donated to a H+ ion or a Lewis acid.

The structure of hyponitrous acid molecule (H2N2O2) is:
  • a)
    Linear (A –B–C–D type) 
  • b)
  • c)
  • d)
Correct answer is option 'C'. Can you explain this answer?

Correct Answer :- C
Explanation : Trans and cis are the two possible structures of hyponitrous acid. White crystals are obtained from trans-hyponitrous which are explosive when dry and it is a weak acid which decomposes to nitrous oxide when in aqueous solution. Sodium salt can be obtained from cis acid.

Hybridizat ion of Ni(II) in K2[NiBr4] is:
  • a)
    dsp2
  • b)
    sp3
  • c)
    sp2d
  • d)
    d3s
Correct answer is option 'B'. Can you explain this answer?

Asf Institute answered
- In K2[NiBr4], the nickel ion is surrounded by four bromide ions.
- The electronic configuration of Ni(II) is 3d8 4s2.
- To form the complex, the nickel ion utilizes one 4s and three 4p orbitals to hybridize into four sp3 hybrid orbitals.
- The hybrid orbitals are then used to form sigma bonds with the four bromide ions.
- Therefore, the hybridization of Ni(II) in K2[NiBr4] is sp3.

The correct order of stability for the given canonical structures is:
  • a)
    I > III > II
  • b)
    III > I > II
  • c)
    II > III > I
  • d)
    II > I > III
Correct answer is option 'B'. Can you explain this answer?

Veda Institute answered
There are a certain set of rules that must be followed in order to check the stability of resonating structures.
These rules have a preference so we have to follow the order:
  • Uncharged species is more stable than charged species.
  • Charged species having more number of covalent bond are more stable.
  • The species in which the octet rule is followed by every atom is more stable than the species in which the octet rule is violated.
  • Species in which opposite charges are closer are more stable than species having same charges closer.
  • Species with negative charge on more electronegative atom while positive charge on more electropositive atom is more stable.
According to above discussion, B is the correct answer.

BF3 is hydrolyzed by H2O, then how many type of acids are expected as products:
    Correct answer is '3'. Can you explain this answer?

    Sravya Mehta answered  •  Jan 25, 2025
    Understanding BF3 Hydrolysis
    When boron trifluoride (BF3) undergoes hydrolysis, it reacts with water (H2O) resulting in the formation of various products. This process involves the interaction of BF3 with water molecules, leading to the generation of acids.
    Types of Acids Produced
    The hydrolysis of BF3 can typically yield three different types of acids:
    • ... more
    • 2. Hydrofluoric Acid (HF): During the hydrolysis, hydrofluoric acid is also produced as a byproduct. This acid is known for its strong reactivity and can cause severe burns. The reaction yields HF alongside boric acid:
      • BF3 + 3 H2O → H3BO3 + 3 HF

    • 3. Bifluoride Ion (HF2-): Under certain conditions, additional hydrolysis can lead to the formation of the bifluoride ion. This ion can be considered as a weak acid, contributing to the overall acidity of the solution:
      • HF + F- → HF2-


    Conclusion
    In summary, the hydrolysis of BF3 produces three types of acids: boric acid, hydrofluoric acid, and the bifluoride ion. Each of these contributes to the overall acidity of the solution formed during the hydrolysis process. Thus, the answer to how many types of acids are expected as products is indeed '3'.

      A chemical reaction is determined by the sum of the exponents in the rate equation. The rate equation is an expression that relates the rate of the reaction to the concentrations of the reactants.

      For example, a generic rate equation may be written as:

      Rate = k[A]^m[B]^n
