Question

write next two compound of these CH4-homologous series​

Answer 1

1. Series of compounds in which the same functional group substitutes for hydrogen in a carbon chain is called a homologous series.

2. For example , all alkanes have similar structures with single covalent bonds and show similar chemical properties so they are grouped together in a homologous series having formula CnH2n+2.

3. The two consecutive members of a homologous series are methane CH4 and ethane C2H6

a. No. of carbons and hydrogen decides its physical properties.

b. The functional group attached to it decides its chemical properties.
