Question

The correct relation between the intensities of inter-molecular attraction $I_s,I_l$ and $I_g$ in solids, liquids and gases respectively, is :

• A. $I_s$<$I_l$<$I_g$
• B. $I_s$>$I_l$>$I_g$
• C. $I_s$=$I_l$=$I_g$
• D. $I_s$>$I_l$<$I_g$

Answer 1

The correct option is B $I_s$>$I_l$>$I_g$

The correct relation between the intensities of inter-molecular attraction $I_s,I_l$ and $I_g$ in solids, liquids and gases respectively, is $I_s>I_l>I_g$.
The solids contain strong intermolecular forces of attraction whereas gases contain weak intermolecular forces of attraction.
