According to Cannizzaro's reaction. $2{\mathrm{C}}_6{\mathrm{H}}_5\mathrm{CHO}+\mathrm{NaOH}\stackrel{50\%\mathrm{NaOH}}{\rightleftharpoons }{\mathrm{C}}_6{\mathrm{H}}_5\mathrm{COONa}+{\mathrm{C}}_6{\mathrm{H}}_5{\mathrm{CH}}_2\mathrm{OH}$ Related Theory Aldehydes containing no $\alpha$-hydrogen atom on warming with $50\%\mathrm{NaOH}$ or $\mathrm{KOH}$ undergo disproportionation i.e. self oxidation reduction known as Cannizzaro's reaction. Caution Aldehydes that contains alpha hydrogen atoms are not involved in Cannizzaro reaction.
