The Correct Option is C

Solution and Explanation

Ethylene dibromide hydrolyse, when boiled with aqueous $ N{{a}_{2}}C{{O}_{3}} $ solution. $ \underset{C{{H}_{2}}Br}{\overset{C{{H}_{2}}Br}{\mathop{|}}}\,\xrightarrow[N{{a}_{2}}C{{O}_{3}}(a)\Delta ]{2H.\,OH}\underset{C{{H}_{2}}OH}{\overset{C{{H}_{2}}OH}{\mathop{|}}}\, $

  • Alcohol is an organic compound used as a solvent that is insoluble in water.
