Question

Which of the following compounds can be used to prepare ethene from ethyl alcohol?

• A. ${Al}_2{O}_3$
• B. $H_2{SO}_4$
• C. $CaO$
• D. Both $A$ and $B$

Answer 1

The correct option is D Both $A$ and $B$

To prepare ethene from ethyl alcohol, dehydration of ethyl alcohol is required. $A{l}_2{O}_3$ and $H_{2}S{O}_4$ both dehydrate the ethanol and gives $ethene$ and $water$ as product.
$HC{H}_2-C{H}_{2}OH\stackrel{H_{2}S{O}_{4}orA{l}_2{O}_3}{\to }C{H}_2=C{H}_2+H_{2}O$
