JEE Advanced 2016 Paper 2 Offline Chemistry - Aldehydes, Ketones and Carboxylic Acids Question 46 English

LiAlH4 in (C2H5)2O
BH3 in THF
NaBH4 in C2H5OH
Raney Ni/H2 in THF

Explanation

Option (A) : LiAlH4 in (C2H5)2 reduces ester ($$-$$COOR), carboxylic acid ($$-$$COOH) epoxide, aldehydes and ketones.

Option (B) : BH3 in THF reduces $$-$$COOH and aldehydes into alcohols. However, it does not reduces esters and epoxides.

Option (C) : NABH4 in C2H5OH reduces only aldehydes and ketones into alcohols, but it does not reduce to others.

Option (D) : Raney Ni/H2 in THF does not reduce to $$-$$COOH, $$-$$COOR and epoxide but it can reduce aldehyde into alcohols.

Hence, options (C) and (D) are correct.
