For a solution formed by mixing liquids $$L$$ and $$M,$$ the vapor pressure of $$L$$ plotted against the mole fraction of $$M$$ in solution is shown in 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)

The IUPAC name(s) of the following compound is (are)

Columns 1, 2 and 3 contain starting materials, reaction conditions, and type of reactions, respectively.

	Column 1		Column 2		Column 3
(I)	Toluene	(i)	NaOH/Br2	(P)	Condensation
(II)	Acetophenone	(ii)	Br2/hv	(Q)	Carboxylation
(III)	Benzaldehyde	(iii)	(CH3CO)2O/ CH3COOK	(R)	Substitution
(IV)	Phenol	(iv)	NaOH/CO2	(S)	Haloform

The only CORRECT combination in which the reaction proceeds through radical mechanism is :

Columns 1, 2 and 3 contain starting materials, reaction conditions, and type of reactions, respectively.
