Question

23. Which of the following statements is correct?
(a) +I group stabilises a carbocation. (b)-I group stabilises a carbocation
(c) +I group stabilises a carbanion. (d) -I group stabilises a carbanion.
24 Which of the following is the strongest acid ?​

Answer 1

Answer:

(a) is correct option

Explanation:

+I effect brings about charge dispersal

thereby making the carbocation stable

Answer 2

Answer:

a) and c)

Explanation:

Carbocation is stabilized by +I group.

Because Carbocation $C^+$ has an excess of positive charge so it needs electrons to stabilize itself and +I groups give electron density to nearby atom. So when +I group is attached to a carbocation its transfers its electron density thus stabilizing the carbocation.

Carbanion is stabilized by -I group.

Because Carbanion $C^-$ has excess of negative charge so it needs to lose electron density to stabilize and -I groups pull electron density from nearby atom so when Carbanion is attached to a -I group it pulls electrons from the carbanion stablizing it.
