Answer» Correct Answer - B When aan acid is heated with `Br_(2)` in the presence P, `alpha`- H atom of the acid is replaced by bromine atom. This reaction is called Hell- Volhard-Zelinsky reaction. `NH_(2)^(-)` is a better nucleophile than `Br^(-)` `RCH_(2)COOH overset(Br_(2)//P) underset("HVZ reaction")to underset((X)) underset(Br)underset(|)(R-CH-COOH) overset("Excess") to underset((Y)) underset(NH_(2)) underset(|) (R-CH-COOH)` |
