Interpretation Introduction

(a)

Interpretation: The structure corresponding to (2E,4E)−octa−2,4−diene in the s−trans conformation is to be drawn.

Concept introduction: The systematic naming of organic compound is given by IUPAC. 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.

The prefix E and Z depends upon the location of the higher priority groups. When two higher priority groups are present on the opposite side then it is an E isomer, whereas when two higher priority groups are present on the same side then it is Z isomer.

The structure corresponding to (2E,4E)−octa−2,4−diene in the s−trans conformation is shown as:

Organic Chemistry, Chapter 16, Problem 16.9P , additional homework tip 1

Explanation of Solution

The given name is (2E,4E)−octa−2,4−diene. The word root used in this is oct. It means structure contains eight carbon atoms. The hydrocarbons that are attached to the longest chain are called substituents and they are written as prefix in alphabetical order. The prefix used is E. Thus, it means that the two double bonds are present on the opposite side.

Thus, the correct structure of (2E,4E)−octa−2,4−diene is shown below.

The prefix E and Z depends upon the location of the higher priority groups. When two higher priority groups are present on the opposite side then it is an E isomer, whereas when two higher priority groups are present on the same side then it is Z isomer.

Answer to Problem 16.9P

The structure corresponding to (2E,4E)−octa−2,4−diene in the s−trans conformation is shown as:

Organic Chemistry, Chapter 16, Problem 16.9P , additional homework tip 1

Explanation of Solution

The given name is (2E,4E)−octa−2,4−diene. The word root used in this is oct. It means structure contains eight carbon atoms. The hydrocarbons that are attached to the longest chain are called substituents and they are written as prefix in alphabetical order. The prefix used is E. Thus, it means that the two double bonds are present on the opposite side.

Thus, the correct structure of (2E,4E)−octa−2,4−diene is shown below.
