1. In bromoethane and chloroethane mixture intermolecular interactions of $A–A$ and $B–B$ type are nearly same as $A–B$ type interactions.
2. In ethanol and acetone mixture $A–A$ or $B–B$ type intermolecular interactions are stronger than $A–B$ type interactions.
3. In chloroform and acetone mixture $A–A$ or $B–B$ type intermolecular interactions are weaker than $A–B$ type interactions.

$2 \mathrm{Fe}^{3+}(\mathrm{aq})+2 \mathrm{I^-}(\mathrm{aq}) \rightarrow 2 \mathrm{Fe}^{2+}(\mathrm{aq})+\mathrm{I}_{2}(\mathrm{aq})$
