Organic Chemistry Some Basic Principles and Techniques - Result Question 59

####65. Which one of the following is a technique most suitable for purification of cyclohexanone from a mixture containing benzoic acid, isoamyl alcohol, cyclohexane and cyclohexanone? [1997]

(a) Crystallization

(b) Sublimation

(c) IR spectroscopy

(d) Gas chromatography

Show Answer

Solution:

  1. (c) 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 appear 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).
