Answer:
SOâ‚‚ would require to overcome dipole-dipole bonding and London dispersion forces
Hâ‚‚Se would require to overcome hydrogen-bonding
Explanation:
Both of these molecules are gaseous but are liquid under pressure
Ion-dipole bonding is present when there are ions present in the liquid. In both the cases, ions are not present hence this bonding is not present in the given molecules.
Hydrogen bonding is present in Hâ‚‚Se, because there is a more electronegative element present than hydrogen. This develops partial charges on both the atoms and consequently attracts hydrogen atom of one molecule to the selenium atom of the other molecule.
London dispersion forces are present between all type of molecules, atoms and ions. These forces are weak but are dominant in molecules having large size. SOâ‚‚ is a large molecule so it will be dominant in it
Dipole-dipole bonding is present in molecules that have polar ends. SOâ‚‚ have polar ends, so this bonding will be present in it
