Question

Question #42ac9

Answer 1

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.
