Interpretation Introduction

a) 2-Methyl-1, 5-hexadiene

Interpretation:

The structure corresponding to the IUPAC name 2-Methyl-1, 5-hexadiene is to be drawn.

Concept introduction:

The longest carbon chain containing the double bond to be chosen. Based on the name of the parent compound – the alkene name ends with the suffix –ene. The chain is to be numbered from the end that gives the lowest number to the carbon in double bond. Substituents are to be numbered according to their positions in the chain and listed alphabetically. The position of the double bond is indicated by giving the number of the first alkene carbon before the name of the parent name. If more than one double bond is present, their positions are indicated with the suffixes -diene, -triene and so on.

To draw:

The structure corresponding to the IUPAC name 2-Methyl-1, 5-hexadiene.

Interpretation Introduction

b) 3-Ethyl-2, 2-dimethyl-3-heptene

Interpretation:

The structure corresponding to the IUPAC name 3-Ethyl-2, 2-dimethyl-3-heptene is to be drawn.

Concept introduction:

To draw:

The structure corresponding to the IUPAC name 3-Ethyl-2, 2-dimethyl-3-heptene.

Interpretation Introduction

c) 2, 3, 3-trimethyl-1, 4, 6-octatriene

Interpretation:

The structure corresponding to the IUPAC name 2, 3, 3-trimethyl-1, 4, 6-octatriene is to be drawn.
