Difference between lialh4 and nabh4
Web1st = LiALH4 is a strong reducing agent then NaBH4 due to difference of electronegitivity between AL and B. 2nd= the carbonyl carbon of esters, amides or carbxylic acids is attached with a atom having lone pair which is in resonance with the double bond of carbonyl group.NABH4 being weaker reducing agent cannot reduce any of these. WebThis reaction can be used to generate hydrogen in the laboratory. LiAlH4 + 4H2O → LiOH + Al (OH)3 + 4H2. The reduction reaction with LiAlH 4 as the reducing agent must be …
