What is another name for formic acid?

Formic acid is chemically known as methanoic acid. It is the simplest carboxylic acid, consisting of a single carbon atom and is represented by the formula HCOOH. The name "methanoic" comes from the Greek word "methy," meaning "a small mass," which reflects its structure as a one-carbon carboxylic acid.

In contrast, the other options represent different carboxylic acids with longer carbon chains. Ethanoic acid, commonly known as acetic acid, has two carbon atoms, while propanoic acid has three, and butanoic acid has four. Understanding these distinctions helps in recognizing functional groups and the nomenclature of organic compounds, particularly in the context of carboxylic acids.
