1-Propanol, also known as propyl alcohol, has the molecular formula C3H8O. To depict its structural formula, we need to understand the arrangement of its atoms.
In 1-propanol, the alcohol functional group (-OH) is attached to the first carbon of a three-carbon chain. The structural formula can be represented as follows:
H H H | | | H - C - C - C - OH | | | H H H
This representation shows that the molecule consists of three carbon (C) atoms, with the first carbon connected to a hydroxyl group (O-H) and the remaining two carbons fully saturated with hydrogen (H) atoms. Thus, in total, it contains 8 hydrogen atoms (C3H8), confirming the molecular formula.
