Question

Which type of isomerism is most common among ethers?
A. Chain
B. Metamerism
C. Position
D. Functional

Answer 1

Hint : Compounds with the same molecular formula but different structures are called isomers. Compounds differ in the nature of functional groups in functional isomerism. While they differ in the nature of alkyl groups attached to the same functional group in metamerism.

Complete step by step solution :
Organic chemistry is the chemistry sub discipline involving the scientific study of the structure, properties and reactions of organic compounds and organic materials. The phenomenon in which compounds having the same molecular formula but different arrangement of carbon atoms in them is called isomerism. Isomers are classified into structural and stereoisomers. Structural isomers are again classified into chain, positional, functional, ring chain, metamerism, tautomerism.
Chain isomerism is the isomerism in which the compounds differ in the nature of carbon chains. E.g. butane has two isomers-butane and 2-methylpropane. In position isomerism, compounds differ in the position of functional groups. E.g. Butene has two isomers-1-butene and 2-butene.
Metamerism is commonly found in ethers. In this isomerism, the nature of alkyl groups may differ. This occurs due to the unequal distribution of carbon atoms on either side of the functional groups. E.g. Diethyl ether and methyl propyl ether are metamerical isomers.
Therefore option B is correct.

Note : Hard soaps are sodium salt and it is moderately soluble in water. E.g. Aleppo soap, Castile soap. Soft soaps are potassium salt and it is soluble in water. E.g. Shampoo, liquid hand wash. Insoluble soaps are calcium or magnesium salts which are used as lubricants.
