Question

Wired Faculty App

The reaction by which benzaldehyde cannot be prepared?

+CrO₂Cl₂ and CS₂ followed by H₃O⁺
+H₂ in presence of anhydrous AlCl₃.
+CO +HCl in presence of anhydrous AlCl₃
+Zn/Hg and Conc. HCl

Solution

+Zn/Hg and Conc. HCl

Thus, from the reagents given in option (d) benzaldehyde is not obtained
