Interpretation Introduction

(a)

Interpretation: The IUPAC name for the given compound is to be stated.

Concept introduction: The systematic naming of organic compound is given by IUPAC nomenclature. The naming of organic compound is done such that the structure of organic compound is correctly interpreted from the name.

Rules for writing IUPAC name from structural formula are:

1. First identify the longest carbon chain.

2. The next step is to identify the groups attached to the longest chain.

3. Identify the position, location, and number of the substituent bonded to the carbon chain.

4. Use prefix di, tri, tetra if same type of substituent is present.

5. Name the substituents in alphabetical order.

Answer to Problem 4.38P

The IUPAC name for the given compound is $6-\text{isopropyl}-3-\text{methyldecane}$.

Explanation of Solution

The given compound is,

Figure 1

The number of carbon atoms present in longest carbon chain is shown below.

Figure 2
