Question

Difference between saturated and unsaturated hydrocarbon in tabular form

Answer 1

Saturated hydrocarbons Unsaturated hydrocarbons.1. In this type, the carbon atoms are connected by a single covalent bond1.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 CnH2n+2 where,n= 1,2,3...2. These double bonded compounds are called Alkene with a general formula CnH2n and the triple bonded compounds are called Alkynes with a general formula CnH2n-23.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 + Cl2 - --> CH3Cl + HCl

CH3Cl + Cl2 -->CH2Cl2 +HCl

CH2Cl2 + Cl2 --> CHCl3 + HCl

 

5. They undergo addition reaction as

CH2=CH2 +H2 -->CH3-CH3

 

6.For example Methane CH4

For example: Ethene CH2=CH2
