Vedclass · Answer

(B) $1$. The starting material is propene $(CH_3CH=CH_2)$.$2$. Hydroboration-oxidation of propene with $(i) B_2H_6$ and $(ii) H_2O_2/NaOH$ gives propan$-1-$ol $(CH_3CH_2CH_2OH)$ as $X$.$3$. Dehydrogenation of propan$-1-$ol $(X)$ using $Cu$ at $573 \ K$ gives propanal $(CH_3CH_2CHO)$ as $Y$.$4$. Propanal $(Y)$ undergoes aldol condensation in the presence of dilute $NaOH$ followed by heating $(\Delta)$ to give the $\alpha,\beta$-unsaturated aldehyde,$2$-methylpent-$2$-enal $(CH_3CH_2CH=C(CH_3)CHO)$ as $Z$.
