m‑chlorobenzaldehyde on reaction with conc. KOH at room temperature gives:
Cannizzaro's reaction
When m - chlorobenzaldehyde is treated with 50% KOH solution, the product(s) obtained is
A tertiary alcohol ‘H’ upon acid catalyzed dehydration gives a product I. Ozonolysis of I leads to compounds J and K. Compound J upon reaction with KOH gives benzyl alcohol and a compound L, whereas K on reaction with KOH gives only M.
The structure of compound I is:
