1.	How will you get the following products with the given reactants ? (A) Acetylene rarr Benzene (B) Phenol rarr Benzene (c) Benzene rarr Tolune (ii) Write any two different componets you get during fractional distillation of Coal Tar at any two different temperature .
Answer» Solution : `underset("(Phenol)")(C_(6)H_(5)OH)+Zn overset(Delta)underset("Dry distillation")rarr underset("(Benzene)")(C_6H_6)+ZnO` ( C) `underset("Benzene")(C_(6)H_(6))+CH_(3)Cl overset("anhydrous"AlCl_3)rarrunderset("(Toluene)")(C_(6)H_(5)CH_3)+HCl` Coal tar is a viscous liquid obtained by the pyrolysis of coal. During fractional distillation, coal tar is heated and ~istills away its volatile compounds, namely, benzene, toluene, xylene in the temperature range of 350 K to 443 K. These vapurs are collected at the upper part of the fractionating COLUMN.
