Question

what is the example of homologous series plz answer

Answer 1

it is series of compound in which the same functional group substitutes for the hydrogen in a carbon chain. ex: alcohol, CH3OH, C2H5OH, C3H7OH, C4H9OH.

Answer 2

Answer:

• A homologous series is a series of compounds, which has the same functional group.
• This also contains similar general formula and chemical properties. Since there is a change in the physical properties, we can say that there would be an increase in the molecular size and mass.

Examples:-

Methane, ethane, propane, butane, etc. are all part of the alkane homologous series.

The general formula of this series is CnH2n+2.

• Methane CH4
• Ethane CH3CH3
• Propane CH3CH2CH3
• Butane CH3CH2CH2CH3.

It can be noticed that there is a difference of −CH2 unit between each successive compound.
