Answer» Correct Answer - D When a mixture of ethyl alcohol (in excess) and conc. `H_(2)SO_(4)` is heated to a tempreture to a temperature below that required to form ethene, intermolecular dehydration occurs instead of intramolecular dehydration. `CH_(3)CH_(2)-OH+H-OCH_(2)CH_(3)overset(Conc. H_(2)SO_(4))(rarr)CH_(3)CH_(2)-O-CH_(2)CH_(3)+H_(2)O` The ether always has a lower boiling point than the parent alcohol and is distilled off as it forms. |
