Assertion (A) states that unsaturated fats are more reactive compared with the saturated fats. This is true. Unsaturated fats contain carbon-carbon double or triple bonds, which are points of unsaturation and are chemically more reactive than the single bonds found in saturated fats, particularly undergoing addition reactions. Reason (R) states that unsaturated fats have only single bonds in their structure. This is false. Unsaturated fats are defined by the presence of one or more double or triple carbon- carbon bonds.
