$X = 	ext{CO, HCl, CuCl}$; $Y = 	ext{Benzyl alcohol}$,$Z = 	ext{Sodium benzoate}$

Vedclass · Answer

(B) The first step is the Gattermann-Koch reaction,where benzene reacts with carbon monoxide $(	ext{CO})$ and hydrogen chloride $(	ext{HCl})$ in the presence of anhydrous aluminum chloride $(	ext{AlCl}_3)$ and cuprous chloride $(	ext{CuCl})$ to form benzaldehyde. Thus,$X = 	ext{CO, HCl, CuCl}$.The second step is the Cannizzaro reaction. Benzaldehyde,which lacks $\alpha$-hydrogen atoms,undergoes self-oxidation and reduction in the presence of concentrated sodium hydroxide $(	ext{NaOH})$ to form benzyl alcohol $(Y)$ and sodium benzoate $(Z)$.

What are $X$,$Y$,and $Z$ in the following reaction sequence respectively?
Benzene $\xrightarrow{X}$ Benzaldehyde $\xrightarrow{\text{Conc. NaOH}, \Delta} Y + Z$
