Answer
An ether is classified as aliphatic ether when two alkyl groups (represented as R) are attached with 'O' atom on both side of O atom by single bond.
General representation: $R-O-R$
An ether is classified as aromatic ether when two aryl groups (represented as 'Ar') are attached with 'O' atom on both side of O atom by single bond.
General representation: $Ar-O-Ar$
An ether is classified as mixed ether when one alkyl group (R) is attached with 'O' atom on one side and one Aryl group (Ar) is attached with 'O' atom on another side by single bond.
General representation: $R-O-Ar$
Example of aliphatic ether: dimethyl ether (IUPAC name: methoxymethane)
Aromatic ether: diphenyl ether (IUPAC name: phenoxybenzene)
Mixed ether: methyl phenyl ether (IUPAC name: methoxybenzene)
Structural formulas are as follows:
Work Step by Step
R = Alkyl group for example $-CH_{3}, -CH_{2}CH_{3} etc.$
Ar = Aryl group for example $-C_{6}H_{5} etc.$
