|
|
CnH2n
|
|
|
CnH2n+1
|
|
|
CnHn+1
|
|
|
CnH2n+2

Explanation:
Detailed explanation-1: -Only single bonds are present in saturated hydrocarbons. I.e. Saturated hydrocarbons are alkanes. The general formula of alkanes is CnH2n+2.
Detailed explanation-2: -Hence, the general formula C n H 2 n + 2 represents alkanes.
Detailed explanation-3: -The general formula of Saturated hydrocarbons is CnH2n.
Detailed explanation-4: -Whenever in a molecule of an alkane there are n carbon atoms, then in this molecule there are exactly 2n+2 hydrogen atoms. There are very many different alkanes with a given number n of carbon atoms (see below), but in all such molecules the number of hydrogen atoms is 2n + 2.
