Chapter 13.10, Problem 13.11PP

Interpretation Introduction

(a)

Interpretation:

The IUPAC name of the following compound should be determined.

  

Concept Introduction:

When the mixture of hydrocarbons from natural resources such as coal or petroleum are separated, certain compounds are emerged with pleasant odors and are thus known as aromatic hydrocarbons.

Hydrocarbons with sigma bonds and delocalization of pi electrons between carbon atoms, thus forms a circle is said to be aromatic hydrocarbons.

Rules of naming aromatic compounds are:

1. Aromatic compounds are named as a benzene derivative.
2. For single substituent, the benzene ring is symmetrical. Thus, all the positions are equivalent.
3. For more than one substituent, the benzene ring is not symmetrical. Thus, numbering will be done from one substituent which is attached to ring to other substituent through shorter path. Numbering should be done in a way that the first substituent gets the lowest number.
4. In naming, the names of substituents are listed in alphabetical order.
