Give the classification of ethers with examples.

(N/A) Ethers are classified into two main categories based on the nature of the alkyl or aryl groups attached to the oxygen atom:
$1$. Symmetrical Ethers (Simple Ethers): In these ethers,the two alkyl or aryl groups attached to the oxygen atom are the same. For example,$CH_3-O-CH_3$ (Dimethyl ether) and $C_6H_5-O-C_6H_5$ (Diphenyl ether).
$2$. Unsymmetrical Ethers (Mixed Ethers): In these ethers,the two alkyl or aryl groups attached to the oxygen atom are different. For example,$CH_3-O-C_2H_5$ (Ethyl methyl ether) and $CH_3-O-C_6H_5$ (Methyl phenyl ether or Anisole).
