Chapter 23, Problem 23.45SP

Interpretation Introduction

Interpretation:

An organic compound can have many structures by which they can be represented, such as molecular formula, Lewis structure, structural formula, line-drawing and condensed structural formula.

Concept introduction:

The ultimate condensed formula is a line-angle formula, in which carbon atoms are implied at the corners and ends of lines, and each carbon atom is understood to be attached to enough hydrogen atoms to give each carbon atom four bonds.

1. The carbon atoms and the hydrogen atoms attached to them are not shown as C and H respectively.
2. Only the bonds between the carbon atoms are shown as lines, single bond as double bond as and triple bond as
   
3. The vertices and end of lines represent the carbon atoms.
4. The valencies on carbon are assumed to be filled by hydrogen atoms.
5. All atoms attached to carbon are shown other than carbon and hydrogen atoms.

Given:

Chemical formula- $C_5{H}_{12}$

To determine:

To draw the straight-chain alkane with the formula $C_5{H}_{12}$ as a condensed structure and as a line drawing.
