What is the decreasing order of strength of the bases `OH^(-), NH_(2)^

1.	What is the decreasing order of strength of the bases `OH^(-), NH_(2)^(-), H - C -= C^(-)` and `CH_(3) - CH_(2)^(-)`A. `CH_(3) - CH_(2)^(-) gt NH_(2)^(-) gt H - C^(-) gt OH^(-)`B. `H - C -= C^(-) gt CH_(3) - CH_(2)^(-) gt NH_(2)^(-) gt OH^(-)`C. `OH^(-) gt NH_(2)^(-) gt H - C -= C^(-) gt CH_(3) - CH_(3)^(-)`D. `NH_(2)^(-) gt H - C -= C^(-) gt OH^(-) gt CH_(3) - CH_(2)^(-)`
Answer» Correct Answer - A order of basic strength `CH_(3) - CH_(2)^(-) gt bar(N)H_(2) gt HC -= C^(-) gt OH^(-)` because their acids have following order of acidic strength `H - OH gt HC -= CH gt NH_(3) gt CH_(3) - CH_(3)` (conjugate base of strong acid is weaker while conjugate base of weak acid is stronger).
