Text Solution

Verified by Experts

The correct Answer is:
A
Both compound `alpha`- hydrogen hence undergo Crossed Cannizzaro reaction.
Inity `OH` attacks at the carbonnyl carbon of `HCHO` than that of `PhCHO` because carbonyl carbon of `HCHO` is
(i) more electronphilic
(ii) less sterically hindered to given hydroxyalkoxide which acts as hydride donor in next step to give sodium formate.
`C_(6) H_(5) CHO - HCHO overset (NaOH) to HCOONa + C_(6) H_(5) CH_(2) OH`
