When benzyl chloride is treated with ethanolic \(\mathrm{KCN}\), followed by acidification, the major product formed is:
1 Benzoic acid
2 Benzyl alcohol
3 Benzyl cyanide
4 Phenyl acetic acid
Explanation:
CHXII12:ALDEHYDES KETONES AND CARBOXYLIC ACIDS
323894
Assertion : Ketones can be converted into acids by haloform reaction. Reason : Addition of Grignard reagents to dry ice followed by hydrolysis gives ketones.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Grignard reagents reacts with dry ice followed by hydrolysis to form carboxylic acids instead of ketones, as the intermediate carboxylate is further hydrolyzed into the carboxylic acid So the option (3) is correct.
