Alkenes have a general formula:
CnH2n+1
CnH2n -2
CnH2n+2
CnH2n
Alkenes are unsaturated hydrocarbons and the number of hydrogen atoms is twice that of carbon atoms i.e. CnH2n.
The hydrocarbon with the general formula CnH2n+2 is an -
2nd member of homologous series having general formula CnH2n−2
The general formula CnH2n for cycloalkanes is the same as that of
