Question

7) Write the chemical reaction showing :
(a) Dehydration of ethanol with concentrated sulphuric acid.
(b) Combustion of ethanol.

Answer 1

Dear Student
(a) dehydration of ethanol
$C_2{H}_{5}OH\underset{{170}^{\circ }C}{\overset{conc{H}_{2}S{O}_4}{\to }}C{H}_2=C{H}_2+H_{2}O$
(b) combustion of ethanol
$C_2{H}_{5}OH+3O_2\to 2C{O}_2+3H_{2}O∆H=-1020Kj/mol$
