cluestion: Explain in terms of structure and bonding, why Iz has higher
boiling point than HI .
ron-polar
Ans: Iy and HI are both simple molecular structures. It is an molecule with
wear ist instanaus -induced dipple forces of atraction while he is a polar Morcule
with permanent dipole - induced dipole forces of attraction. I,
has
cleathens than HI
- were the electen excloud of Ig is more polarisable. Therefore
more energy is needed to overcome the IP - ID foros in Iy than the Pd fores
more
in HI.
