Chapter 6, Problem 32P

(a)

Interpretation Introduction

Interpretation:

The structure of 3-ethyl-2-iodopentane should be drawn.

Concept Introduction:

There are few steps in IUPAC nomenclature,

1. Find the longest carbon chain in the molecule and name it.
2. Number the longest carbon chain in such a way that the halogen atoms get the lowest number.
3. If there are multiple halogen atoms from same atom, a prefix as di, tri, tetra is added to denote the number of halogen atoms.
4. Different types of halogens are named in alphabetical order.
5. Position of the halogen atom is indicated by writing the number of carbon atom it is attached before the name of the parent hydrocarbon.
6. The name is ended as a normal alkane.

(b)
