Choose the correct order arranged in decreasing order of basicity

A

`CH-=C^(-) gt CH_(3)O^(-) gt OH^(-)`

B

`OH^(-) gt CH_(3)O^(-) CH - = C^(-)`

C

`CH_(3)O ^(-) gt OH^(-) gt CH -= C^(-)`

D

`CH_(3)O^(-) gt CH-= C^(-) gt OH^(-)`

Text Solution

Verified by Experts

The correct Answer is:
A
The strengths of conjugate acids of the given bases are in the order : `H_(2)OgtCH_(3)OHgtHC-=CH`
Stronger the acid, weaker is the conjugate base. Hence, decreasing order of basicity is
`HC-=C^(-)CH_(3)O^(-)gtOH^(-)`
