Is this the right way to write the structual and the chemical formula for propane?

P P P P
P C C C C P

Pretend that there are bonds in between each of the letters. Chemical Formula: C3P8. Thanks for checking this out.

Propane is C3H8

No, the way you have written the structural formula and the chemical formula for propane is incorrect.

The correct structural formula for propane is:

H H H
| | |
H – C – C – C – H
| | |
H H H

Propane is an organic compound consisting of three carbon atoms (C) and eight hydrogen atoms (H). Each carbon atom is bonded to three hydrogen atoms, and the three carbon atoms are connected in a chain.

Therefore, the correct chemical formula for propane is C3H8, not C3P8. In the chemical formula, the number following each element represents the number of atoms of that element in one molecule of the compound. In this case, there are three carbon atoms and eight hydrogen atoms in one molecule of propane.
