(b) Shows negative deviation from Raoult’s law
Explanation:
Shows negative deviation from Raoult’s law. If the attraction between different molecules, for example between HCl and H2O molecules, is stronger, the escaping tendency from the solution to the vapour phase will be smaller, then the partial vapour pressure will be smaller than predicted by Raoult’s law and the system exhibits a negative deviation.
