What is meant by homologous series of carbon compounds?
What are homologous series of carbon compounds?
Advertisements
उत्तर
Organic compounds that have similar general formulas belong to a series called the homologous series. The chemical properties of the organic compounds in the homologous series are the same because of the presence of the same functional group.
Alkanes, alkenes, alkynes, etc. form such series in which their respective members differ in mass by 14 atomic mass units. Each member in the series differs from the previous one by a CH2 group.
