: Depression in freezing point is a colligative property it depends upon the number of particles. Thus, as the number of particles increases, freezing point decreases. Thus $0.1 \mathrm{M} \mathrm{Al}_2\left(\mathrm{SO}_4\right)_3$ shows minimum freezing point.

Which of the following is an anti-knocking compound?
1 TEL
2 LTC
3 Freon
4 Gasoline
Explanation:
: Tetra Ethyl lead is an organ metallic compound containing the toxic metal lead that for much of the $20^{\text {th }}$ century was the chief anti-knocking compound for automotive gasoline or petrol. It is used for raising octane number of petrol. Tetraethyl lead in petrol was used as anti-knocking agent which creates lead pollution in order to avoid lead pollution. The substitute of TEL is used in unleaded petrol.
