Less reactivity of saturated hydrocarbons is due to the presence of single bonds between carbon atoms. Paraffins (alkanes) may have straight chain or branched chain isomers which have different parent names.

In the following questions a statement of Assertion (A) followed by a...
Explanation:
Assertion and reason are both related to the chemical reactivity of saturated hydrocarbons. Let's break down the explanation:
Assertion (A): Saturated hydrocarbons are chemically less reactive.
- Saturated hydrocarbons are hydrocarbons that contain only single bonds between carbon atoms. These molecules are saturated with hydrogen atoms, meaning they cannot undergo additional chemical reactions easily.
- The presence of only single bonds makes saturated hydrocarbons less reactive compared to unsaturated hydrocarbons which contain double or triple bonds.
Reason (R): All isomeric paraffins have the same parent name.
- Isomers are compounds that have the same molecular formula but different structural arrangements. Paraffins are a group of saturated hydrocarbons.
- While isomeric paraffins may have the same parent name (e.g., ethane, propane, butane), they have different structures and physical properties due to their different arrangements of carbon and hydrogen atoms.
Explanation of Correct Answer:
- The correct answer is option 'C' because the assertion is true - saturated hydrocarbons are indeed less reactive due to the presence of only single bonds. However, the reason is false - isomeric paraffins may have the same parent name, but they have different structures and properties. This means that the reason does not correctly explain why saturated hydrocarbons are less reactive.
In conclusion, while the assertion about the reactivity of saturated hydrocarbons is true, the reason provided about the naming of isomeric paraffins does not correctly explain this property.
