The condensed structural formula for acetic acid (the main component in vinegar) is CH3COOH.

This formula is a shorthand way of representing the complete structural formula (see above picture).

The first carbon atom is surrounded by three hydrogen atoms. The second carbon atom is surrounded by one oxygen atom and a OH group. Hence its formula is CH3COOH
