Chapter 4, Problem 1PP

Interpretation Introduction

Interpretation:

The condensed and bond-line structural formula for all the constitutional isomers with molecular formula ${\text{C}}_{\text{7}}{\text{H}}_{\text{16}}$, are to be written.

Concept introduction:

Constitutional isomers are the isomers in which the molecular formula remains same but the arrangements of groups or atoms in the structure are different.

Mostly organic compound is represented by the bond line structural formulas.

In bond line formula each bond is represented by a line.

At the end of each line if no atom is shown than a carbon atom is present.

Condensed structural formula is defined as the formula in which all the carbon-carbon bonds are eliminated and the hydrogen atom written just after the carbon atom.

Answer to Problem 1PP

Solution:

Bond-line structural formula:

Condensed formula:

Explanation of Solution

Given: The molecular formula is ${\text{C}}_{\text{7}}{\text{H}}_{\text{16}}$.

In ${\text{C}}_{\text{7}}{\text{H}}_{\text{16}}$, there are seven carbon atoms and 16 hydrogen atoms. The bond-line structural formula for all the nine constitutional isomer is as follows:

All the above structures have same molecular formula, $C_7{H}_{16}$. The condensed structural formula for all the above mentioned nine constitutional isomers is as follows:
