Base strength of the following
(i) `H_(3)C CH_(2)^(-)` , (ii) `H_(2)C=CH^(-)`
(iii) `HC-=C^(-)`

A

`b gt a gt c`

B

`c gt b gt a`

C

`a gt c gt b`

D

`a gt b gt c`

Text Solution

Verified by Experts

The correct Answer is:
D
Stronger the conjugute acid, weaker will be corresponding base. Acidity of conjugate acids of given carbanions is `(c) gt (b) gt (a)`. Therefore, the base strength is `(a) gt (b) gt (c)`.
