What is the decreasing order of strength of the bases OH, `NH_(2)` , H-C=C and `CH_(3),-CH_(2)`,

Options

A. `CH_(3)-CH_(2)^(-) gt NH_(2)^(-) gt H-C equiv C^(-) gt OH^(-)`
B. `H-C equiv C^(-) gt CH_(3)-CH_(2)""^(-) gt NH_(2)^(-) gt OH^(-)`
C. `OH^(-) gt NH_(2)^(-) gt H-C equiv C^(-) gt CH_(3)-CH_(2)^(-)`
D. `NH_(2)^(-) gt H-C equiv C^(-) gt OH^(-) gt CH_(3)-CH_(2)^(-)`

Answer

A

Explanation

`CH_3 CH_2^(-) gt NH_2^(-) gt H-C ^(@) C ^(-) gt OH^(-0`
