Aldehydes undergo disproportionation reaction in presence of aqueous NaOH. Simultaneou oxidation and reduction of a compound is scientifically called as disproportionation. Aldehydes having no alpha-hydrogen show this rection called Cannizzaro's reaction. Few exception are also there to this represented as : C_(6)H_(5)CHO+C_(6)H_(5)CHO overset(NaOH)underset(Delta)to C_(6)H_(5)COONa+C_(6)H_(5)CH_(2)OH Intramolecular Cannizzaro's reaction is also possible. Answer the following questions : Mixture of C_(6)H_(5)CHO and HCHO is treated with NaOH then Cannizzaro's reaction involves:

Answer»
