It undergoes Cannizzaro reaction

Vedclass · Answer

(B) Step $1$: Ozonolysis of $C_2H_4$ $(CH_2=CH_2)$ gives formaldehyde $(HCHO)$ as $P$.Step $2$: Reaction of $HCHO$ with $CH_3MgBr$ followed by hydrolysis gives ethanol $(CH_3CH_2OH)$ as $Q$.Step $3$: Oxidation of ethanol $(CH_3CH_2OH)$ with $PCC$ gives acetaldehyde $(CH_3CHO)$ as $R$.$R$ is $CH_3CHO$,which contains $\alpha$-hydrogens. Therefore,it cannot undergo the Cannizzaro reaction. It gives a positive Tollen's test,iodoform test,and undergoes aldol condensation. Thus,the incorrect statement is that it undergoes the Cannizzaro reaction.

Consider the following sequence of reactions. The incorrect statement about $R$ is:
