1. They have the same general formula
2. They have similar chemical properties
3. They show a gradual change in their physical properties.
They are said to be homologous because they have similar structures.
All the families of organic compounds exist as a homologous series (A series having a difference of 'CH2' unit between two consecutive members) the main homologous series-es are Alkanes, Alkenes, Alcohols and Carboxylic acids (Fatty acids).
Chemical compounds (organic) placed in a homologous series have a general chemical formula. The common example is alkenes.

describe a chemical test you would use to show the difference between an isomer and a homologous series
A homologous series is a family of organic compounds that: *have the same general formula. *have similar chemical properties and *show a gradual increase in physical properties such as melting and boiling point.
A hydrocarbon that possesses one double bond belongs to the next homologous series called alkenes.
FIRSTLY THE VISCOSITY IS "the state of being thick, sticky, and semifluid in consistency, due to internal friction."THE VISCOSITY INCREASES UP THE HOMOLOGOUS SERIES BECAUSE IT IS STICKY DUE TO FRICTION- Alodia Gosiengfiao
