1.	The acid strength of active methylene group in A) CH_3COCH_3COOC_2H_5 B) CH_3COCH_2COCH_3 C) C_2H_5 OO C CH_2COOC_2H_5 decreases as
Answer» ` a gt c gt B` `a gt b gt c ` `b gt a gt c ` `c gt a gt b` SOLUTION :The ACID strength of active METHYLENE group is `H_3C -overset(O)overset(\|\|)C-CH_2-overset(O)overset(\|\|)C-CH_3 gt H_3C-overset(O)overset(\|\|)C-CH_2-overset(O)overset(\|\|)C-OC_2H_5 gt H_5C_2-O-overset(O)overset(\|\|)C-CH_2-overset(O)overset(\|\|)C-OC_2H_5` Because ester grop has O-R group which decreases electron WITHDRAWING nature of carbonyl group.
