Answer:
Correct Answer: 60.(c)
Solution:
$IR$ spectroscopy is used for the purification of cyclohexanone from a mixture of benzoic acid, isoamyl alcohol, cyclohexane and cyclohexanone. Because in this method, each functional group appears at a certain peak. So, cyclohexanone can be identified by carbonyl peak.
An amyl alcohol is any one of $8$ alcohols with the formula $C_5 H_{12} O$ (alkanol with $5$ carbons).
