QJEEAdv16Ch7266: JEE Advanced 2016 Chemistry - Class 12 JEEAdv16Ch7266 Solution: Reagent(s) which can be used to bring about the following…

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.
