Chapter 22, Problem 1PE

Interpretation Introduction

Interpretation:

The molecular formula and the condensed structural formula for the given organic compounds are to be given.

Concept Introduction:

The molecular formula indicates the total number of atoms involved in a molecule of a substance.

The condensed structural formula of a molecule does not contain any branching above or below. It is a system of writing organic structures in a line of text.

Answer to Problem 1PE

Solution:

a) ${\text{C}}_{\text{6}}{\text{H}}_{\text{14}}$, ${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{3}}$

b) ${\text{C}}_{\text{6}}{\text{H}}_{\text{14}}$, ${\left({\text{CH}}_{\text{3}}\right)}_2{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}{\left({\text{CH}}_{\text{3}}\right)}_2$

c) ${\text{C}}_2{\text{H}}_3{\text{Cl}}_3$, ${\text{ClCH}}_{\text{2}}{\text{CHCl}}_2$

Explanation of Solution

a)

The molecular formula of the given organic compound consists of 6 carbon atoms and $14$ hydrogen atoms that can be represented as follows:

${\text{C}}_{\text{6}}{\text{H}}_{\text{14}}$

The condensed structural formula for the given organic compound contains 6 carbon atoms and $14$ hydrogen atoms. All carbon and hydrogen atoms are linked together by a single bond and it can be represented as follows:

${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{3}}$

b)

The molecular formula of the given organic compound consists of 6 carbon atoms and $14$ hydrogen atoms that can be represented as follows:

${\text{C}}_{\text{6}}{\text{H}}_{\text{14}}$

The condensed structural formula for the given organic compound contains 6 carbon atoms and $14$ hydrogen atoms.

All carbon and hydrogen atoms are linked together by a single bond and it can be represented as follows:

${\left({\text{CH}}_{\text{3}}\right)}_2{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}{\left({\text{CH}}_{\text{3}}\right)}_2$

c)

The molecular formula of the given organic compound consists of two carbon atoms, $3$ hydrogen atoms and $3$ chlorine atoms that can be represented as follows:

${\text{C}}_2{\text{H}}_3{\text{Cl}}_3$

The condensed structural formula for the given organic compound contains 2 carbon atoms, $3$ hydrogen atoms and $3$ chlorine atoms. All carbon, hydrogen and chlorine atoms are linked together by a single bond and it can be represented as follows:

${\text{ClCH}}_{\text{2}}{\text{CHCl}}_2$
