The Cannizaro reaction is not given by

Options

ATrimethyl acetaldehyde
BAcetaldehyde
CBenzaldehyde
DFormaldehyde

Correct answer

B. Acetaldehyde

Step-by-step solution

(CH 3 ) 3 C − CHO Trimethyl   acetaldehyde CH 3 CHO Acetaldehyde Ph − CHO Benzaldehyde HCHO Formaldehyde Cannizaro reaction is given by only those aldehydes which does not have α - hydrogen atom. As such acetaldehyde has alpha hydrogen so will not give Cannizaro reaction.
