When an electrolyte is dissociated in solution, the van't Hoff's factor (i) is
1 $>1$
2 $<1$
3 $=0$
4 $=1$
Explanation:
When an electrolyte is dissolved in the solution, it breaks into ions and hence the Van't Hoff factor will be greater than 1 ( $i>1)$.

Which of the following compound possesses the $\mathrm{C}-\mathrm{H}$ bond with the lowest bond dissociation energy?
1 Toluene
2 Benzene
3 n-pentane
4 2, 2-dimethyl propane
Explanation:
Toluene has the lowest $\mathrm{C}-\mathrm{H}$ bond dissociation energy compare to other three The $\mathrm{C}-\mathrm{H}$ bond of the methyl group is in hyper conjugation with benzene nucleus. Hence it is easy to break.

0.1 M solution of which of the following has almost unity degree of dissociation ?
1 Ammonium chloride
2 Potassium chloride
3 Sodium acetate
4 All of the above
Explanation:
Among the given only potassium chloride $(\mathrm{KCl})$ is a strong electrolyte, so its degree of dissociation is almost unity.

$\Delta x=$ (hydration energy) - (lattice energy), for a salt $\Delta x$ is found to be $-500 \mathrm{kcal} \mathrm{mol}^{-1}$. Then, on increasing the temperature, its solubility in water
1 increases
2 decreases
3 remains same
4 increases initially and then decreases
Explanation:
In this reaction, heat is evolved during the dissolution, so solubility decreases with rise in temperature.
