1.	When carbon tetrachloride is treated with excess of Benzene in presence of AlCl_3, the productformed is.
Answer» Only`(C_6H_5)_3 C Cl` Only `(C_6H_5)_4` C A MIXTURE of a and b None of the two Solution :Fourth chlorine atomof the `C Cl_4` cannot be replaced by phenyl group because the CARBOCATION required for the introduction of the fourth phenyl group is too stable to react with benzene . `(C_6H_3)_3 C Cl overset(AlCl_3)to underset("Highly stable")((C_6H_5)_3 C^(oplus) AlCl_4^(Ɵ))` Due to steric FACTOR 4th nucleo philic cannot attack atcarbon atom.
