Propane Chemical Formula Derivation
To find the chemical formula of propane, we use the general formula for alkanes, which is:
$ C_nH_{2n+2} $
The prefix "prop-" in propane indicates that the molecule contains 3 carbon atoms. Therefore, in this case, $n=3$.
Substituting $n=3$ into the alkane formula:
- Number of Carbon atoms = $n = 3$
- Number of Hydrogen atoms = $2n + 2 = 2(3) + 2 = 6 + 2 = 8$
Combining the carbon and hydrogen atoms gives the chemical formula for propane:
$ C_3H_8 $
This matches Option B.
