Carbon-oxygen double bond are easily reduced by NaBH_(4) or LiAlH_(4). The actual reducing agent in these reduction is hydride ion (H^(-)). The metal-hydrogen bond in LiAlH_(4) is more polar than metal-hydrogen bond in NaBH_(4). As a result LiAlH_(4) is strong reducing agent than NaBH_(4). Esters, carboxylic acids, amides cannot be reducted by NaBH_(4). The carbonyl group of amide to methylene group by LiAlH_(4). 'X' , Identify X :
