JEE Advance - Chemistry (2016 - Paper 2 Offline - No. 15)
Reagent(s) which can be used to bring about the following transformation is(are)
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.
