Chapter 18, Problem 40E

Interpretation Introduction

Interpretation:

The structural formulas for all alkane that contain four carbon atomsare to be drawn.

Concept introduction:

The general molecular formula for alkanes is ${\text{C}}_n{\text{H}}_{2n+2}$.

The structural formula not only shows the number and type of atom but also the structure.

Structural formulas are two dimensional –representation.

Bonding in atomsis also shown by structural formulas.

The isomers are the compounds that have the same formula but have a different arrangement of the atoms. The isomers also differ from each other in the properties. The structural isomers are the ones, which have different bonding patterns and different spatial arrangement.
