During the reaction between carbonyl compounds with ammonia derivatives, a proper pH is required. Select the correct reasons.A. The increase positive charge on the C atom of `(C=O)` group for the better attack of nucleophilic centre of ammonia derivative, a small amount of acid is needed.B. With excess of acid, ammonia derivatives form their salts and act as strong nucleophilies.C. With excess of acid, ammonia derivatives form their salts and cannot act as nucleophilies.D. The proper pH required for these reactions is nearly `3.5`. |
