Give the names and structural formula of the first three members of homologous series of alkene.

Open in App

Solution

A series of compounds with same functional group that differs by a $- C H_{2}$ unit is known as homologous series.

The first three members of homologous series of alkenes are Ethene, Propene and Butene. Their structural formula are:
$C H_{2} = C H_{2}, C H_{2} = C H - C H_{3}, C H_{2} = C H - C H_{2} - C H_{3}$ respectively.

Give the names and structural formula of the first three members of homologous series of alkene.

A series of compounds with same functional group that differs by a −CH2 unit is known as homologous series. The first three members of homologous series of alkenes are Ethene, Propene and Butene. Their structural formula are: CH2=CH2,CH2=CH−CH3,CH2=CH−CH2−CH3 respectively.
