Right answer is (b) PCl3 does not react with organic compounds

Easy explanation: Phosphorus trichloride is widely used as an important reagent in organic chemistry for replacing hydroxyl groups by chlorine atoms in organic reactions. For example, ethanol reacts with phosphorus trichloride to form chloroethane and phosphorous acid.

3CH3CH2OH + PCl3 → 3CH3CH2Cl + H3PO3.
