(a)

Interpretation Introduction

Interpretation:

The name of the compound has to be given.

Concept Introduction:

Rules for naming compound:

1. 1) The carbon atoms in the longest chain have to be counted.
2. 2) The substituents have to be identified and counted.
3. 3) The backbone carbon atoms have to be numbered by assigning the lowest number from the starting end.

(b)

Interpretation Introduction

Interpretation:

The structural formula of $\text{5-ethyl-2,2-dimethyloctane}$ has to be written.

Concept Introduction:

Structural formula:  A structural formula consists of symbols for the atoms connected by short lines that represent chemical bonds-one, two or three standing lines for single, double or triple bonds respectively.

Rule of writing structural formula:

1. 1) The longest chain of carbon atom has to be drawn.
2. 2) The carbon atoms have to be numbered and the substituents are added accordingly to the number given in the name.
3. 3) The hydrogen atoms as needed to give each carbon atom a valence of four have to be added.
