Differences between saturated and unsaturated hydrocarbon?

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.
