H-bond is the strongest intcrmolccular force All are different with 1, 0 and 2 lone pairs of electrons at central atom.

Q. Amongst $H_{2} O$ , $H_{2} S$ , $H_{2} S e$ and $H_{2} T e$ , the one with the
highest boiling point is

$H_{2} O$ because of hydrogen bonding

$H_{2} T e$ because of higher molecular weight

$H_{2} S$ because of hydrogen bonding

$H_{2} S e$ because of lower molecular weight
