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:
- (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).
