Answer
Molecular Formula: $C_8H_{16}$
Lewis (left) and line (right) structure:
Work Step by Step
- The Lewis Structure.
1. Draw 8 carbons making a circle, with single bonds represented by 2 electrons.
2. Add the hydrogens. Since each carbon is already making 2 bonds, they will have 2 hydrogens each, to complete 4.
- The Line Structure.
Since the only molecules are carbon and hydrogen, and there are no double or triple bonds, the structure of a cyclooctane is just an octagon.
- Molecular Formula:
Simple cyclo saturated hydrocarbons are described by this general formula.
$C_nH_{2n}$
Since it is a cyclo$oct$ane, n = 8.
$C_8H_{16}$
