How will you prepare methanol from formaldehyde without using a reducing agent.

Answer»

Solution :CANNIZZARO reaction is a DISPROPORTIONATION reaction in which one molecule of an aldehyde is reduced while the other is oxidised.
`underset("Formaldehyde")(2H-overset(O)overset(||)(C)-H) + underset((50%))(NaOH)to underset("METHANOL")(CH_(3)OH)+underset("Sod. formate")(HCOONa)`
Here, a CONC. solution NaOH is used which is not a reducing agent.
