Q. The reaction of PCl3 with PhLi in 1:3 molar ratio yields X as one of the products, which on further treatment with CH3I gives Y. The reaction of Y with n-BuLi gives product Z. The products X, Y and Z, respectively, are
(A) [PPh4]Cl, [Ph2P=CH2] and Ph2P(n-Bu)
(B) PPh3, [Ph3PI](CH3) and Ph2P(n-Bu)3
(C) PPh3, [Ph3P(CH3)]I and Ph3P=CH2
(D) [PPh4]Cl, [Ph3P=CH2] and [Ph3P(n-Bu)]Li
Ans: PPh3, [Ph3P(CH3)]I and Ph3P=CH2
