Give any five differences between aromatic and aliphatic ethers.

Solution

Aromatic ethers Aliphatic ethers
The lone pair of electrons on $O$ atom is delocalised over benzene nucleus. The lone pair of electrons on $O$ atom cannot be delocalised
The bond between $O$ and aromatic $C$ is difficult to break. The bond between $O$ and aliphatic $C$ is easy to break.
They are water-insoluble. Low molecular weight aliphatic ethers are water soluble.
They have high boiling points. They have low boiling points.
They can undergo electrophilic aromatic substitution. Substitution of $H$ atoms is not observed.
