Interpretation Introduction

(a)

Interpretation: The structure corresponding to 3ethyl2methylhexane is to be drawn.

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 structural formula from IUPAC are:

1. First identify the word root for the given compound.

2. The suffix used in the compound like –ene.

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

Answer to Problem 4.40P

Organic Chemistry, Chapter 4, Problem 4.40P , additional homework tip  1

Explanation of Solution

The given IUPAC name is 3ethyl2methylhexane.

Rules for writing structural formula from IUPAC are

1. First identify the word root for the given compound.

2. The suffix used in the compound like –ene.

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

The given name is 3ethyl2methylhexane. The word root used in this is hex. It means structure contains six carbon atoms. The hydrocarbons that are attached to the longest chain are called substituents and they are written as prefix in alphabetical order. Therefore, the name suggests that one isopropyl substituents is attached to the third carbon atom and one methyl substituent is attached to second carbon atom.

Thus, the correct structure of 3ethyl2methylhexane is shown below.
