Assertion: tert-Butyl carbanion is less stable than methyl carbanion.
Reason: The `+1`-effect of the `CH_(3)` groups tends to stablize the tert-butyl carbanion.

Why is 1^@ carbanion more stable than a 2 carbanion ?

Why 1^@ carbocation more stable than a 2^@ carbanion ?

(A) Tertiary butyl carbonion is more stable than methyl carbanion. (R) +I effect of the three methyl groups in tertiary butyl carbanion tends to make it more stable than methyl carbanion.

The greater stability of tert-butyl carbocation than methyl carbocation can be explained on the basis of

Assertion : Acetic acid is weaker acid than CH_3 CH_2 COOH. Reason : due to +I effect of methyl group.

Assertion: tert-butylbromide undergoes S_(N)1 nucleophilic substitution readily than n-butyl bromide. Reason: It proceeds by the formation of stable carbocation.

Assertion: tert-butylbromide undergoes S_(N)1 nucleophilic substitution readily than n-butyl bromide. Reason: It proceeds by the formation of stable carbocation.
