Which type of isomerism is most common among ethers?

A)  Metamerism    

B)  Functional

C)  Chain                                   

D)  Position

Correct Answer: A

Solution :

                Ethers show metamerism. Metamerism               arises when a polyvalent functional group (e.g. etc.) is attached to different alkyl groups but the molecular formula remains same e.g., \[{{C}_{2}}{{H}_{5}}-O-{{C}_{2}}{{H}_{5}}\]and \[C{{H}_{3}}-O-{{C}_{3}}{{H}_{7}}\]
