This discussion on What are homologous series? Apart from being the largest Class 10 community, EduRev has the largest solved Within a given homologous series the chemical properties of the compounds are essentially all alike, and the physical properties vary in a continuous and predictable manner. Homologous series, any of numerous groups of chemical compounds in each of which the difference between successive members is a simple structural unit. Homologous series of inorganic compounds include the phosphoric acids, the silicic acids, and the phosphonitrilic chlorides. EduRev is a knowledge-sharing community that depends on everyone being able to pitch in when they know something. A homologous series (homos is Greek for “the same as”) can be defined as the group of compounds in which the various members have similar structural features and similar chemical properties and the successive members differ in their molecular formula by one methylene (CH 2) group. Such series are most common among organic compounds, the structural difference being a methylene group, as in the paraffin hydrocarbons, or alkanes; the normal primary alcohols, or 1-alkanols; and the normal carboxylic acids, or alkanoic acids.
