Which of the following chemical reaction is true?(a) \(C_2 H_2+ 2Cl_2 \, ^{\underrightarrow{BaCl_2}}\,C_2 H_2 Cl_2\)(b) \(C_2 H_2+ 2Cl_2\, ^{\underrightarrow{BaCl_2}}\,C_2 H_2 Cl_4\)(c) \(C_2 H_2 Cl_4\, ^{\underrightarrow{BaCl_2}}\,C_2 HCl_3+ HCl \)(d) \(C_2 H_2 Cl_4\, ^{\underrightarrow{FeCl_3}}\,C_2 HCl_3+ HCl\)I have been asked this question during a job interview.Enquiry is from C1 Compounds in portion Synthetic Organic Chemical Industries of Chemical Technology

Answer»

Correct OPTION is (C) \(C_2 H_2 Cl_4\, ^{\underrightarrow{BaCl_2}}\,C_2 HCl_3+ HCl \)

To explain I would say: The correct chemical equation is \(C_2 H_2 Cl_4\, ^{\underrightarrow{BaCl_2}}\,C_2 HCl_3+ HCl \) as Ferric chloride is USED as catalyst in the reaction of ACETYLENE and chlorine to give tetra chloro ETHANE whereas barium chloride is used as catalyst in the reaction to produce tri chloro ethylene from tetra chloro ethane.
