Question
Give a reason for the following:
Ethoxy ethane does not react with sodium, but ethanol does.
Solution
Ethyl alcohol reacts with sodium metal due to the presence of an active hydrogen atom. In contrast, diethyl ether cannot react with sodium metal because it lacks a replacement hydrogen atom.
\[\ce{\underset{Ethyl alcohol}{2CH3CH2OH} + 2Na -> 2CH3CH2ONa + H2}\]
\[\ce{\underset{Diethyl ether}{(CH3CH2)2O} + Na -> No reaction}\]
