How many hydrogen atoms does a molecule of acetic acid contain?
Four
The correct answer is Four.
The acidity of carboxylic acids is due to the polar nature of the O-H bond in the carboxyl group, which allows the hydrogen atom to be donated as a proton ($\text{H}^+$). Other examples of carboxylic acids include formic acid ($\text{HCOOH}$), propanoic acid ($\text{CH}_3\text{CH}_2\text{COOH}$), and butanoic acid ($\text{CH}_3\text{CH}_2\text{CH}_2\text{COOH}$). Counting hydrogen atoms in these molecules follows the same principle: sum up the hydrogens in the alkyl group (R) and the single hydrogen in the $\text{COOH}$ group.
