Here's how I do it.
Explanation:
Bond line notation is a shorthand way of writing organic structural formulas.
The rules for hydrocarbons are:
- There is a carbon at every vertex and the end of every line.
- Only the bonds between the carbon atoms are shown as lines.
- Any unfilled valences on carbon are assumed to be filled by hydrogen atoms.
EXAMPLE
Draw the bond line structure of 2,2,4-trimethylpentane.
Solution
**Step 1. Draw a zig-zag line containing five carbon atoms.
Step 2. Number the carbon atoms from one end to the other.
The direction doesn't matter.
**Step 3. Put two methyl groups on carbon 2 and one methyl group on carbon 4.
Step 4. Remove the numbers.
And you have your structure.
