Question

what is homologus series write is characteristics of this group

Answer 1

Homologous series is a series of hydrocarbons which contain same functional group but the preceding and succeeding members differ by CH2 or 14 amu. Characteristics of this series are-
1.it have same functional group
2.Two members differ by 14 amu
3.With increase in series, the Melting point and boiling point increase.
4.All members have same genral formula.

Answer 2

A series of saturated or unsaturated compounds where all members have the same functional group.,general formula and similar chemical properties and preceeding and succeeding members differ by - CH2- unit is homologous series.
Characterstics:
1. All members have same functional group.
2. Each member differ by - CH2- unit.
3. Each member differ by 14u.
4. All members have same general formula and similar chemical properties.

Hope it helps.
