Assertion (A): Unsaturated fats are more reactive compared with the saturated fats. Reason (R): Unsaturated fats have only single bonds in their structure.

aBoth A and R are individually true and R is the correct explanation of A
bBoth A and R are individually true but R is not the correct explanation of A
cA is true but R is false
dA is false but R is true
✓ Correct answer: c) A is true but R is false
ExplanationSaturated fats are typically solid at room temperature and are found in animal products like butter, lard, and fatty cuts of meat, as well as some plant oils like coconut and palm oil.They are composed of fatty acids with no double bonds between carbon atoms, making them less reactive.Unsaturated fats are liquid at room temperature and are mainly found in plant-based oils (such as olive, sunflower, and canola oil) and fish.They contain one or more double bonds between carbon atoms which introduce “kinks” in the structure making them more reactive and beneficial for heart health when consumed in moderation.Assertion (A) is true: Unsaturated fats have at least one double bond between carbon atoms, making them more reactive.These double bonds are sites where chemical reactions can occur more easily compared to the single bonds in saturated fats.Reason (R) is false: Unsaturated fats contain at least one double bond in their carbon chain, not only single bonds.Saturated fats have only single bonds.387
