Out of a straight chain alkane and a straight chain alkene having the same number of carbon atoms, which has a higher octane number?

Explanation

To determine which has a higher octane number between a straight chain alkane and a straight chain alkene with the same number of carbon atoms, we can follow these steps:

### Step 1: Understand Octane Number
The octane number is a measure of a fuel's ability to resist knocking during combustion. Fuels with higher octane numbers are more stable and provide better performance in engines.

**Hint:** Remember that the octane number indicates fuel performance and stability.

### Step 2: Identify the Hydrocarbons
