- A.Formic acid
- B.
- C.Acetic acid
- D.Formaldehyde oxime
Show correct answer & step-by-step solution
Correct answer: B —
Solution
- Formaldehyde has no alpha-hydrogens and undergoes the Cannizzaro reaction.
- One molecule is reduced to methanol and one is oxidized to formate.
- The reaction is .
- Hence the answer is (B).
