$$Glucose \xrightarrow [ ]{ HCN } X\xrightarrow [ ]{ Hydrolysis } Y\xrightarrow [ Heat ]{ HI } Z$$ Identify $$Z$$.

A2- Iodoheptane
BHeptane-2-ol
C2-Iodohexane
DHeptanoic acid
Correct Answer

Solution

Answer: $$(D)$$ Heptanoic acid Glucose react with $$HCN$$ to give cyanohydrin which gives heptanoic acid on hydrolysis followed by heating with HI. $$\underset{\left( Glucose \right)}{CHO-{\left( CHOH \right)}_{4}-C{H}_{2}OH} \xrightarrow{HCN} \underset{\left( \text{Glucose Cyanohydrin} \right)}{CN-{\left( CHOH \right)}_{5}-C{H}_{2}OH} \xrightarrow{{{H}_{3}O}^{+}} COOH-{\left( CHOH \right)}_{5}-C{H}_{2}OH$$ $$COOH-{\left( CHOH \right)}_{5}-C{H}_{2}OH \xrightarrow[\Delta]{HI} \underset{\left( \text{Heptanoic acid} \right)}{COOH-{\left( C{H}_{2} \right)}_{5}-C{H}_{3}}$$
