The correct order of increasing basicity...

The correct order of increasing basicity of the given conjugate bases `(R=CH_(3))` is

A

`RCObarO lt HC-=barC lt barNH_(2) lt barR`

B

`RCObarO lt HC-=barC lt barR lt barNH_(2)`

C

`barR lt HC -=barC lt RCObarO lt barNH_(2)`

D

`RCObarO lt barNH_(2) lt HC-=barC lt barR`

Text Solution

Verified by Experts

The correct Answer is:
A

Acidic strength order
`CH_(3)-underset(O)underset(||)(C)-OH gt HC-=CH gt NH_(3) gt CH_(4)`
Basic order of conjugate bases is
`CH_(3)COO^(oplus) lt HC-=C^(oplus) lt overset(oplus)(N)H_(2) lt overset(oplus)(C)H_(3)`.
