Predict the order of base strength of anions from the reactions given below. `HC=CH+LiNH_(2)` hArr HC-= C^(-)Li^(+)+NH_(3)` `HC-=C Li+H_(2)O hArr HC-=CH+LiOH`A. `OH^(-) lt HC-=C^(-) lt NH_(2)^(-)`B. `HC-= C-lt OH^(-)lt NH_(2)^(-)`C. `OH^(-)lt NH_(2)^(-) lt HC-=C^(-)`D. `NH_(2)^(-) lt OH^(-) lt HC-=C^(-)` |

Answer» Correct Answer - A A stonger acid replaces a weaker acid from its salt. Hence, `HC -= CH gt NH_(3) (` acidic strength `)` and `H_(2)O gt HC -=CH. ` `:. H_(2)OgtHC -= CH gt NH_(3)(` acidic strength order `)` Hence, for conjugate bases `: OH^(-)HC-=C^(-)ltNH_(2)^(-)`( basic strength order) |
