Final answer:

Butyric acid is a carboxylic acid with a linear molecular structure. It is not an unsaturated fatty acid or an aromatic compound.

Step-by-step explanation:

Butyric acid, CH3CH2CH2CO2H, is a carboxylic acid. It has a linear molecular structure, as indicated by the arrangement of the carbon and hydrogen atoms in a straight line. It is not an unsaturated fatty acid, as it does not contain any double bonds. Additionally, it is not an aromatic compound.
