Chapter 11, Problem 11A.25E

(a)

Interpretation Introduction

Interpretation:

The structural formula of the branched hydrocarbon with formula ${\text{C}}_{\text{4}}{\text{H}}_{\text{10}}$ has to be drawn.

Concept Introduction:

Structural isomers:  Structural isomers of the compounds have same molecular formula but difference in the spatial arrangement of atoms.

Structural formula:  Structural formulas identify the location of chemical bonds between the atoms of a molecule.  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.

(b)

Interpretation Introduction

Interpretation:

The structural formula of the structural isomers with formula ${\text{C}}_{\text{4}}{\text{H}}_{\text{9}}\text{Cl}$ has to be drawn.

Concept Introduction:

Refer to part (a).
