For a solution formed by mixing liquids ...

For a solution formed by mixing liquids L and M, the vapour pressure of L plotted against the mole fraction of M in solution is shown is the following figure. Here `x_(L)` and `x_(M)` represent mole fractions of L and M, respectively, in the solution. The correct statement (s) applicable to this system is (are)

A

The point Z represents vapour pressure of pure liquid M and Raoult's law is obeyed from `x_(L) = 0` to `x_(L) = 1`

B

Attractive intermolecular interaction between `L-L` in pure liquid L and `M-M` in pure liquid M are stronger than those between L-M when mixed in solution

C

The point Z represents vapour of pure liquid M and Raoult's law is obeyed when `x_(L) rarr 0`
