Question

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

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

Answer 1

The correct option is A

$H_{2}O$, because of hydrogen bonding

There is intermolecular in Hydrogen Bonding in water.
