1000 `"cm"^(3)` of propane is burnt completely in oxygen.
Draw the electronic structure of propane.

Explanation

To draw the electronic structure of propane (C₃H₈), we need to follow these steps:

### Step 1: Identify the molecular formula
Propane is an alkane with three carbon atoms. The molecular formula is C₃H₈.

### Step 2: Determine the number of valence electrons
- Carbon (C) has 4 valence electrons. Since there are 3 carbon atoms in propane, the total number of valence electrons from carbon is:
\[
