Identify the compound that does not exhibits structural isomerism:-
Correct answer: C. 2-Butene
- A. 2-Pentanone
- B. Phenol
- C. 2-Butene
- D. Lactic acid
Explanation
A Reaction which involves simple proton transfer in an intramoleculer fashion is called tautomerism.Hence lactic acid,phenol,2-pentanone will show ketonol tautomerism but 2-butene will not. 2-butene may exist as cis and trans isomers.This cis isomer has two methyl groups on the same side and the trans isomer has the two methyl groups on the opposite sides.Due to restricted rotation around double bond it exhibits geometrical isomerism.

About Fundamental Principles of Organic Chemistry
Organic chemistry begins with carbon compounds classified by carbon skeleton, saturation and functional group. Work includes identifying groups such as hydroxyl, carbonyl, carboxyl and amino, applying basic nomenclature, and distinguishing structural, geometric and optical isomers, where the same molecular formula does not necessarily mean the same structure or properties.
