Question

Compared with its corresponding unsaturated fatty acid, a saturated fatty acid has _____.

Answer 1

Answer: more hydrogen

Explanation:

Saturated fatty acids are defined as the fatty acids in which a single bond is present between carbon and carbon atoms and hydrocarbon chain is attached to carboxylic group. Example: $C_{18}H_{34}O_2$

Unsaturated fatty acids are defined as the fatty acids which have double or triple covalent C-C bonds and hydrocarbon chain is attached to carboxylic group. Example: $C_{18}H_{32}O_2$

Thus a saturated fatty acid has more hydrogens than unsaturated fatty acid.
