JEE Main 2024 — 1 February, Shift 1 — Question 64
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : has lower boiling point than .
Reason (R): In liquid state molecules are associated through vander waal's forces, but molecules are associated through hydrogen bonding.
In the light of the above statements, choose the most appropriate answer from the options given below:
- Option A:
Both (A) and (R) are correct and (R) is not the correct explanation of (A)
- Option B:
(A) is not correct but (R) is correct
- Option C:
Both (A) and (R) are correct but (R) is the correct explanation of (A)
- Option D:Correct
(A) is correct but (R) is not correct
Answer: D
Step-by-step solution
Unlike molecules are not associated through hydrogen bonding in liquid state.
That is why the boiling point of is lower than .
