Chapter 4, Problem 4.23YT

Interpretation Introduction

Interpretation:

It is to be shown that the given molecule is not a constitution isomer of the other two.

Concept introduction:

Compounds with the same molecular formula but different connectivity is called constitutional isomers. To identify constitutional isomers, first check for the formula. If the molecular formula of both the compounds is the same, then select the longest continuous chain of the carbon atoms. Finally, compare the attachments. If the locant number and attached substituent are different for both molecules, then and then only are they constitutional isomers. If the attached substituent and the locant number are the same, then they are not constitutional isomers. The conformational isomers or conformers are the isomers that can be interconverted to each other due to rotation about carbon-carbon single bond.
