Why alcohols cannot be used as solvents with (a) Grignard reagent and (b) LiAlH_(4).

Answer»

Solution :Alcohols are sufficiently acidic to react with strong BASES `R^(-) : and H^(-)` :
`CH_(3)OH+H-overset(H)overset(|)UNDERSET(H)underset(|)C-MgX RARR CH_(4)+(CH_(3)O)-MgX`
`4CH_(3)OH+LiAlH_(4)rarr 4H_(2)+LiAl(OCH_(3))_(4)`
