1.	Which of the following reagents does not reduce the CO group of carboxylic acids to CH2 groups to form alcohols?(a) LiAlH4-ether(b) B2H6-THF(c) H2-CuCr2O4(d) NaBH4I got this question in homework.Enquiry is from Carboxylic Acids Chemical Reactions topic in division Aldehydes, Ketones and Carboxylic Acids of Chemistry – Class 12
Answer» Correct choice is (d) NaBH4 Best EXPLANATION: CARBOXYLIC acids on reduction with LiAlH4, B2H6 or H2 in the PRESENCE of suitable MEDIUM, are reduced to alcohols. The COOH group is reduced to CH2OH group. SODIUM borohydride cannot reduce the carboxyl group.
