Q. No.Given below are two statements :
In the light of the above statements, choose the most appropriate answer from the option given below:
1. Both Statement I and Statement II are incorrect.
2. Statement I is correct but Statement II is incorrect.
3. Statement I is incorrect but Statement II is correct.
4. Both Statement I and Statement II are correct.
| Statement I : | The boiling point of three isomeric pentanes follows the order \(\text { n-pentane }>\text { isopentane }>\text { neopentane }\) |
| Statement II : | When branching increases, the molecule attains the shape of sphere. This results in smaller surface area for contact, due to which the intermolecular forces between the spherical molecules are weak, thereby lowering the boiling point. |
In the light of the above statements, choose the most appropriate answer from the option given below:
1. Both Statement I and Statement II are incorrect.
2. Statement I is correct but Statement II is incorrect.
3. Statement I is incorrect but Statement II is correct.
4. Both Statement I and Statement II are correct.
