Chapter 20, Problem 2ALQ

Interpretation Introduction

(a)

Interpretation:

The structure of the incorrectly named compound should be determined along with the correct name of the compound.

2-ethyl-3-methyl-5-isopropyl hexane

Concept Introduction:

Compounds consist of carbon and hydrogen is known as hydrocarbons.

Rules of naming saturated and unsaturated hydrocarbons are:

1. First choose the longest continuous chain of carbon atoms known as parent chain.
2. The numbering of parent chain should be done in a way that the substituents, double bond and triple bond get the lowest number.
3. In case of alkene, “ene” is used at the end of the name and in case of alkyne, “yne” is used at the end of the name.
4. The appropriate name should be given to every alkyl group and denote its position on the parent chain with the number.
5. The alkyl groups are written in alphabetical order.

Interpretation Introduction
