Chemistry - Carboxylic acid and their Derivatives Question with Solution | TestHub

The general formula for saturated fatty acid is${\mathrm{C}}_{\mathrm{n}}{\mathrm{H}}_{2\mathrm{n}+1}\mathrm{C}\mathrm{O}\mathrm{O}\mathrm{H}$.

Among the given acids, only${\mathrm{C}}_{17}{\mathrm{H}}_{35}\mathrm{C}\mathrm{O}\mathrm{O}\mathrm{H}$satisfy this formula, hence it is a saturated fatty acid.
