What is the correct decreasing order of boiling points for the hydrides of Group 16 elements? — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Generally, boiling points increase down the group due to increasing molar mass and Van der Waals forces ($H_2Te > H_2Se > H_2S$). However, $H_2O$ has an anomalously high boiling point that exceeds all others in the group due to extensive intermolecular hydrogen bonding.
