Final answer:
Formic acid is also known as methanoic acid and should not be confused with acetic acid, which is ethanoic acid. It is the simplest carboxylic acid and has connections to ant stings.
Step-by-step explanation:
Another name for formic acid is methanoic acid. Formic acid, with the chemical formula HCO₂H, is the simplest carboxylic acid and was historically called methanoic acid due to its association with ants (from the Latin word 'formicus'). It plays a role in the sting of ants and wasps and has a distinct odor associated with ants. Acetic acid, another carboxylic acid, is referred to as ethanoic acid and is best known as the main component of vinegar. Formic acid should not be confused with acetic acid, ethanol, ethyl acetate, or acetone, which are all different compounds.
