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^(-) gt 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 strength of the conjugate acids of the given base are
`H_(2)O gt CH_(3)OH gt HC -= CH`
Stronger the acid, weaker is the conjugate base, hence decreasing order of basicity is `HC -= C^(-) gt CH_(3) O^(-) gt OH^(-)`
