An ether is more volatile than an alcohol having the same molecular formula. This is due to
dipolar character of ethers
alcohols having resonance structures
inter-molecular hydrogen bonding in ethers
inter-molecular hydrogen bonding in alcohols.
As we learnt in
Physical properties of ether -
– Insoluble in water except dimethyl ether.
– Show dipole moment due to C - O polar bond.
– Boiling points of ether are lower than isomeric alcohol.Due to the presence of H-bonding in alcohol.
-
In ether there is no inermolecular hydrogen bond, whereas in alcohol intermolecular hydrogen bond is present which makes them less volatile and have high boiling point.
