hope it's help u

Answer 2

Alkanes are the group of hydrocarbons in which only single bonds are required between two carbon atoms or carbon and hydrogen atom to fulfill the valencies of all carbon atoms.

The homogeneous series of Alkanes are ;

CH4 ---> methane
C2H6 ---> ethane
C3H8 ---> propane
C4H10 ---> butane
C5H12 ---> pentane
C6H14 ---> hexane
C7H16 ---> heptane
C8H18 ---> octane
C9H20 ---> nonane
C10H22 ---> Decane
