JEE Main 2025 — 3 April, Evening Shift — Question 1

Given below are two statements : one is labelled as Statement I and the other is labelled as Statement II:

Statement I: Hyperconjugation is not a permanent effect.

Statement II: In general, greater the number of alkyl groups attached to a positively charged C -atom, greater is the hyperconjugation interaction and stabilization of the cation.

In the light of the above statements, choose the correct answer from the options given below :

  1. Option A:

    Both Statement I and Statement II are true

  2. Option B:

    Statement I is false but Statement II is true

    Correct
  3. Option C:

    Both Statement I and Statement II are false

  4. Option D:

    Statement I is true but Statement II is false

Answer: B

Step-by-step solution

Hyperconjugation is a permanent effect. With increase in number of α−H\alpha-\mathrm{H} which increases

with number of alkyl groups attached to positively charged C, hyperconjugation increases.
