What happens when acetic acid is
reduced by lithium aluminium hydride

Explanation

Acetic Acid from Methyl Magnesium Bromide
Methyl magnesium bromide when reacts with dry ice (solid `CO_2`) in etheral solution produce salts of carboxlic acid, which on acidiffication with mineral acids give corresponding carboxylic acids.
