Given below are two statements: Statement (I): The boiling points of alcohols and phenols increase with increase in the number of C-atoms. Statement (II): The boiling points of alcohols and phenols are higher in comparison to other class of compounds such as ethers, haloalkanes. In the light of the above statements, choose the correct answer from the options given below:

1. Both Statement I and Statement II are false
2. Statement I is false but Statement II is true
3. Statement I is true but Statement II is false
4. Both Statement I and Statement II are true

Correct answer: Both Statement I and Statement II are true

Solution

Both statements are accurate because the boiling points of alcohols and phenols do increase with more carbon atoms due to greater van der Waals forces, and they generally have higher boiling points than ethers and haloalkanes due to the presence of hydrogen bonding.
