1.	Which of the following statement regarding PCl3 is false?(a) PCl3 forms metal chlorides on heating with finely divided metals(b) PCl3 does not react with organic compounds(c) PCl3 is a colourless pungent smelling liquid(d) PCl3 boils at 347 KThis question was addressed to me in an online quiz.Question is from P-Block Elements in chapter P-Block Elements of Chemistry – Class 12
Answer» 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.
