Vedclass · Answer

(A) $1$. Reaction with $HCN$ followed by hydrolysis $(H_{3}O^+)$ adds a carbon atom to the carbonyl group of Fructose $(C_{6}H_{12}O_{6})$,resulting in a heptonic acid derivative $(A)$ with the formula $C_{7}H_{14}O_{8}$.$2$. Reduction of Fructose with $NaBH_{4}$ followed by heating with $HI/P$ reduces all hydroxyl and carbonyl groups to a hydrocarbon chain. Since Fructose is a hexose,the final product $B$ is $n$-hexane $(C_{6}H_{14})$.$3$. Therefore,$A = C_{7}H_{14}O_{8}$ and $B = C_{6}H_{14}$.

The formulas of $A$ and $B$ for the following reaction sequence are:
