Which of the following group has maximum hyperconjugation effect but minimum inductive effect

Question

Which of the following group has maximum hyperconjugation effect but minimum inductive effect (A) - CH 3 (B) - CH 2- CH 3 (C) - CD 3 (D)

Tardigrade Admin · Accepted Answer

- CH 3 show maximum hyperconjugation effect but minimum inductive inductive effect. For Hyperconjugation :- C-H bond energy should be low (more propto- H more hyper conjugation with less C-H bond energy) For Inductive Effect :- no. of carbon and branching increases inductive effect.

Q. Which of the following group has maximum hyperconjugation effect but minimum inductive effect

$- C H_{3}$

$- C H_{2} - C H_{3}$

$- C D_{3}$

$- C H_{3}$ show maximum hyperconjugation effect but minimum inductive inductive effect.
For Hyperconjugation :- $C - H$ bond energy should be low (more $\propto - H$ more hyper conjugation with less $C - H$ bond energy)
For Inductive Effect :- no. of carbon and branching increases inductive effect.

Q. Which of the following group has maximum hyperconjugation effect but minimum inductive effect

−CH3​

−CH2​−CH3​

−CD3​

−CH3​ show maximum hyperconjugation effect but minimum inductive inductive effect. For Hyperconjugation :- C−H bond energy should be low (more ∝−H more hyper conjugation with less C−H bond energy) For Inductive Effect :- no. of carbon and branching increases inductive effect.

$- C H_{3}$

$- C H_{2} - C H_{3}$

$- C D_{3}$
