Question

Which of the following compounds will undergo Cannizzaro reaction?

• A. $\mathrm { CH } _ { 3 } \mathrm { CHO }$
• B. $\mathrm { CH } _ { 3 } \mathrm { COCH } _ { 3 }$
• C. $\mathrm { C } _ { 6 } \mathrm { H } _ { 5 } \mathrm { CHO }$
• D. $\mathrm { C } _ { 6 } \mathrm { H } _ { 5 } \mathrm { CH } _ { 2 } \mathrm { CHO }$

Answer 1

Answer: (C)

$\mathrm { C } _ { 6 } \mathrm { H } _ { 5 } \mathrm { CHO }$

Answer 2

: Aldehydes with no $\alpha - H$ atom undergo Cannizzaro reaction on heating with conc. Alkali solution. Hence, only $\mathrm { C } _ { 6 } \mathrm { H } _ { 5 } \mathrm { CHO }$will undergo the reaction.
