Some of the reactions were done to synthesize compounds that were used to conduct other reactions. The experiments were also used to analyze the efficiency of these reactions.


All the statements given below are true, except:

A CH3COOH can undergo hydrogen bonding
B The melting point of carboxylic acids are higher than that of comparable alcohols
C The carbonyl group in carboxylic acids are more electrophilic than that of ketones
D In carboxylic acids, resonance is possible
Ans. C Choice A is true. Carboxylic acids can undergo hydrogen bonding. Choice B is also true and so is Choice D. Choice C is not true. In fact, the hydroxyl group makes its carbonyl group less electrophilic. In a ketone there is no hydroxyl group and that makes its carbonyl group more electrophilic than that of a carboxylic acid.
