JEE · NEET Previous Year Question
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.
choose the correct answer from the options given below:
Topic: JEE PYQ
Answer: B. Full step-by-step solution below.
- ABoth Statement I and Statement II are false
- BBoth Statement I and Statement II are true
- CStatement I is false but Statement II is true
- DStatement I is true but Statement II is false
Correct answer: B
Solution
(b) Statement I is correct as boiling point of alcohol phenols increase with increase in thenumber of -atoms due to increase in van der Waals forces. Statement II is correct, since alcohols phenols have intermolecular H -bonding therefore their boiling points are higher in comparison to other class of compounds such as ethers, haloalkanes.
