Question

(a) Define the term functional group. Identify the functional group present in 0) H—C—H (ii)Hicic=o (b) What happens when 5% alkaline KMnO,1 solution is added drop by drop to warm ethanol taken in a test tube? State the role of alkaline KMnO4 solution in this reaction.

Answer 1

Explanation:

a-

In organic chemistry, functional groups are specific substituents or moieties within molecules that are responsible for the characteristic chemical reactions of those molecules.

b-

e KMNO4 turns to green K2MNO4 which then again gets converted to MNo2 which discharges brown colour which serves as the test for unsaturation for ethene
