Cannizzaro’s reaction is not given by:
 

1.  2.
3. HCHO 4. CH3CHO

Hint: Compound does not have α hydrogen.

The necessary condition for the Cannizzaro reaction is the absence of α-hydrogen atom. So  CH3CHO will not give Cannizzaro reaction while the other three compounds have no α-hydrogen. Hence, they will give Cannizzaro reaction.
