Differentiate between saturated and unsaturated hydrocarbons giving one example of each.

Difference between saturated and unsaturated hydrocarbons are as follows:

Saturated hydrocarbons	Unsaturated hydrocarbons.
1. In this type, the carbon atoms are connected by a single covalent bond	1.In this type, the carbon atoms are connected by multiple bonds like double (=) or triple (≡) bonds.
2.These single bonded compounds are called as Alkene, with a general formula C_nH_2n+2where,n= 1,2,3...	2. These double bonded compounds are called Alkene with a general formula C_nH_2nand the triple bonded compounds are called Alkynes with a general formula C_nH_2n-2
3.These are less reactive as they are attached with strong ∂ sigma bonds which are not broken easily.	3. these are more reactive as they contain one or two pi-bonds which are easily broken so these compound are not very stable as alkanes.
4. They dont undergo hydrogenation.	4. They can be hydrogenated by passing Hydrogen gas as they have less hydrogen than saturated hydrocarbons.
5.They involve substitution reactions Ex. CH₄ + Cl_{2 - -->} CH₃Cl + HCl CH₃Cl + Cl_{2 -->}CH₂Cl₂ +HCl CH₂Cl₂+ Cl_{2 -->} CHCl₃ + HCl
	5. They undergo addition reaction as CH₂=CH₂ +H₂ -->CH₃-CH₃
6.For example Methane CH₄	For example: Ethene CH₂=CH₂

Saturated Organic Compounds	Unsaturated Organic Compounds
These organic compounds contain single carbon-carbon covalent bond.	These organic compounds contain at least one double or triple covalent bond.
Due to the presence of all single covalent bonds, these compounds are less reactive.	Due to the presence of double and triple bonds, these compounds are more reactive.
Saturated compounds undergo substitution reactions. Example:	Unsaturated compounds under go addition reactions. Example:
The number of hydrogen atoms is more when compared to its corresponding unsaturated hydrocarbon.	The number of hydrogen atoms is less when compared to its corresponding unsaturated hydrocarbon.
