Base strength of
`(1) H_(3)Coverset(Theta)(C)H_(2), (2) H_(2)C=overset(Theta)(C)H` and (3) `H-C-=overset(Theta)(C)` is in the order of

A

`(3)gt(2)gt(1)`

B

`(1)gt(3)gt(2)`

C

`(1)gt(2)gt(3)`

D

`(2)gt(1)gt(3)`

Text Solution

Verified by Experts

The correct Answer is:
C
The stronger is the acid, the more is the nucleophilicity of conjugate base.
Acidic nature: `CH-=CHgtCH_(2)=CH_(2)gtCH_(3)-CH_(3)`
Conjugate basic: `CH-=C^(-) lt CH_(2)=CH^(-) lt CH_(3)-CH_(2)^(-))` nature.
