Arrange the following (i) -CHO,-COCH_(3),-COOH,-COCl,-CONH_(2),-COOCH_(3),-COO^(-) in dereasing order of nucleophilic addition. (ii) CH_(3),CHO,CH_(3)COCH_(3),HCHO,C_(2)H_(5)COCH_(3)in decreasing order of nucleophilic addition. (iii)CH_(3)COCH_(2)CHO,CH_(3)COCH_(3),CH_(3)CHO,CH_(3)COCH_(2)COCH_(3) in increasing order of expected enol content. (iv) CH_(3)CHO,C_(6)H_(5)CHO,(CH_(3))CO,FCH_(2)CHO in decreasing order of reactivity in decreasing order of reactivity

Answer»

Solution :(i) The tendency of nucleophilic addition INCREASES with increases of positive partial CHARGE on the carbonyl carbon atom.
