Question

Among $H_{2}O,H_{2}S,H_{2}Se$ and $H_{2}Te$, the one with the highest boiling point is:

• A. $H_{2}O$ because of hydrogen bonding interactions
• B. $H_{2}Te$ because of its higher molecular weight
• C. $H_{2}S$ because of hydrogen bonding interactions
• D. $H_{2}Se$ because of its lower molecular weight

Answer 1

The correct option is A $H_{2}O$ because of hydrogen bonding interactions

Among $H_{2}O,H_{2}S,H_{2}Se$ and $H_{2}Te$, $H_{2}O$ has the highest boiling point because they are linked by hydrogen bonding interactions.
