state gov RPSC 2nd Grade Senior Teacher Mock Test Series 2025 Chemistry Organic Chemistry – Some Basic Principles and Techniques
Given below are two statements:
Statement I : The boiling point of three isomeric pentanes follows the order n-pentane > isopentane > neopentane
Statement II : When branching increases, the molecule attains a 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 options given below:
1
Both Statement I and Statement II are correct
2
Both Statement I and Statement II are incorrect
3
Statement I is correct but Statement II is incorrect
4
Statement I is incorrect but Statement II is correct
