X underset ( 170^(@) C )overset( Conc. H_2SO_4) to Y underset( C Cl_4)

1.	X underset ( 170^(@) C )overset( Conc. H_2SO_4) to Y underset( C Cl_4)overset(Br_2) toQ underset (Delta)overset( alc. KOH) to Rifx is ethyl alcohol correct statement (s) about R is / are A) it decolourizes Bayer's reagent B) it gives benzene when subjected to polymerization C) it gives red precipitate with ammonical Cu_2Cl_2 D) it gives ethylene on hydrogenation in the presence of Lindlar's catalyst
Answer» A , B & C <BR>B,C & D A , B, C & D A, B & D Solution :`underset((X))(C_2H_5OH) underset(170^(@)C)overset(conc. H_2SO_4)tounderset((Y))(CH_2 = CH_2) overset(Br_2// C Cl_4)to underset(Br)underset(\|)CH_2 - underset(Br)underset(\|)CH_2 underset(Delta)overset(alc.KOH)to underset("Ethyne (R)")(CH -=CH)`
