Saturated Hydrocarbons
The carbon atoms are joined by a single covalent bond like | | -C-C- | |
Unsaturated Hydrocarbons
A double or triple bond links at least one pair of carbon atoms. | | C=C | |
Saturated Hydrocarbons
All four valence electrons are linked with hydrogen atoms.
Unsaturated Hydrocarbons
At least one pair of carbon atoms are not completely linked with hydrogen atoms.
Saturated Hydrocarbons
These hydrocarbons are less reactive.
Unsaturated Hydrocarbons
These hydrocarbons are more reactive.
Saturated Hydrocarbons
They undergo a substitution reaction.
Unsaturated Hydrocarbons
They undergo an addition reaction.
Saturated Hydrocarbons
Example:
Alkanes such as methane, ethane, and propane are saturated hydrocarbons.
Unsaturated Hydrocarbons
Example:
Alkenes such as ethane and propene are examples of unsaturated hydrocarbons.
Saturated Hydrocarbons
Alkanes general formula.
CnH2n+2
Unsaturated Hydrocarbons
Alkenes the general formula of
CnH2n
Unsaturated Hydrocarbons
Alkynes such as ethyne and propyne are also unsaturated hydrocarbons with the general formula
CnH2n–2
