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)^(-),HC-=C^(-) and CH_(3)CH_(2)^(-)?
Answer» `CH_(3)CH_(2)^(-) gt NH_(2)^(-) gt HC -=C^(-) gt OH^(-)` `HC -= C^(-) gt CH_(3)CH_(2)^(-) gt NH_(2)^(-) gt OH^(-)` `OH^(-) gt NH_(2)^(-) gt HC -= C^(-) gt CH_(3)CH_(2)^(-)` `NH_(2)^(-) gt HC-=C^(-) gt OH^(-) gt CH_(3)CH_(2)^(-)` Answer :A
