What is the decreasing order of strength...

What is the decreasing order of strengths of the following bases ?
`overset (Ө) OH, NH_2^ (Ө), H-C -= C^ (Ө) `, and `CH_3 - CH_2^ (Ө)`.

A

`Cl^(-) gt CH_(3)COO^(-) gt NH_(3)`

B

`CH_(3)COO^(-) gt NH_(3) gt Cl^(-)`

C

` CH_(3)COO^(-) gt Cl^(-) gt NH_(3)`

D

`NH_(3) gt CH_(3)COO^(-) gt Cl^(-)`

Text Solution

Verified by Experts

The correct Answer is:
D
Acid strength: `HCl gt CH_(3)COOH gt NH_(4)^(+)`
Conjugate Base strength `Cl^(-) lt CH_(3)COO^(-) lt NH_(3)`
