Q1 FREE PREVIEW

Given below are two statements :
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

[JEE Main 2025, 3 Apr (Shift 2)]

a

Statement I is true but Statement II is false

b

Both Statement I and Statement II are false

c

Statement I is false but Statement II is true

d

Both Statement I and Statement II are true

✓ Correct answer: c)

Statement I is false but Statement II is true

Explanation

Hyperconjugation is a permanent effect because no external reagent is required. Therefore, Statement I is false and Statement II is true.
More alkyl groups mean more α-hydrogen atoms, leading to greater hyperconjugation, which results in greater stability of the carbocation.
