Question

From the following compounds which shows Cannizzaro's reaction?

$A)C{H}_{3}C{H}_{2}CHO$ $B)CHC{l}_{2}CHO$

$C\left)C\right(C{H}_3{)}_{2}CHO$ $D)C_6{H}_{5}CHO$

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

Answer 1

Answer: (B)

$C,D$

For Cannizaro's reaction:

Primary condition $=$ should not have any $\alpha$ - hydrogen.

In $C(C{H}_3{)}_{2}CHO$ and $C_6{H}_{5}CHO$, we have $\alpha$ -hydrogen $=0$

So, molecule C, D will undergo Cannnizzaro's reaction.
