Priyanshu kumar Best Answer
Option A I and II
yes sir explanation
Both the options (1) and (2) are colligative properties Colligative properties depends on the ratio of number of solute particles to the solvent particles in a solution Colligative properties include freezing point depression, osmotic pressure, vapor pressure lowering, and boiling point elevation. Colligative properties also depends upon the number of particles in the solution. Methanol is a non-electrolyte which cannot be considered as colligative property.
got this shristy?
lekin sir option 3 me freezing ka use toh hua h
methanol non electrolyte hai na
