Solution
Correct Answer:
H₂O
The boiling point of hydride group members usually increases down the group due to increasing van der Waals forces. However, H2O is an anomaly.
- Oxygen is highly electronegative and small in size, allowing it to form strong Intermolecular Hydrogen Bonds.
- Each water molecule can form up to 4 hydrogen bonds, creating an extensive network.
- H2S,H2Se,H2Te cannot form effective hydrogen bonds as S,Se,Te are larger and less electronegative.
- Consequently, H2O has a much higher boiling point (100∘C) than its congeners.
This easy difficulty chemistry question is from the chapter chemical bonding and molecular structure, covering the topic of hydrogen bonding. It appeared in the 2025 exam.
