NEET 2024 Chemistry Boiling Point Trends Assertion Reason Question
Given below are two statements:
Statement I: The boiling point of hydrides of Group 16 elements follow the order H₂O > H₂Te > H₂Se > H₂S.
Statement II: On the basis of molecular mass, H₂O is expected to have lower boiling point than the other members of the group but due to the presence of extensive H⁻bonding in H₂O, it has higher boiling point. In the light of the above statements,
choose the correct answer from the options given below:
Statement I is true but Statement II is false.
Statement I is false but Statement II is true.
Both Statement I and Statement II are true.
Both Statement I and Statement II are false.
Correct Answer
Detailed Explanation
H₂O has a higher boiling point due to hydrogen bonding, despite its lower molecular mass compared to other Group 16 hydrides.
