Question

Which of the following compounds would undergo Cannizzaro reaction?

A) $HCHO$

B) $C_6{H}_{5}CHO$

C) $C{l}_{3}C-CHO$

D) $(C{H}_3{)}_{3}C-CHO$

• A. $A$ and $B$ only
• B. $B$ and $C$ only
• C. $C$ and $D$ only
• D. $A,B,$ and $D$

Answer 1

The correct option is D $A,B,$ and $D$

Carbonyl compounds having no $\alpha -$hydrogen will undergo Cannizzaro reaction.

Out of the above-given options, A, B and D none of them have alpha hydrogen. So, all can undergo Cannizzaro reaction.

Option C compound is known as chloral because in presence of base chloral gives chloroform, which is not Cannizzaro product.

$CC{l}_{3}CHO+O{H}^{-}\to CHC{l}_3$
