Question

The substance Terylene is obtained by the condensation polymerization of benzene-1, 4-dioc acid and ethane-1, 2-diol.

In not more than two steps, give the equation with reagents and reaction condtions for the conversion of ethane to ethan-1, 2-diol.

Write the formula of the polymer that is obtained in the condensation reaction.

Answer 1

$1. \ \ \ C_2H_6 \ \ \ \underrightarrow{\ Br_2, \ Sunlight, Alcoholic\ KOH \ }\ \ CH_2=CH_2$

$CH_2 = CH_2\ \ \underrightarrow{\ KmnO_4, \ OH, \ cold \ H_2O\ } \ \ CH_2(OH)_2$

$2. \ \ \ \ C_6H_4(COOH)_2 + CH_2(OH)_2 \longrightarrow (C_{10}H_8O_4) _n$
