What is a hydrocarbon? Give any 3 examples.
The compounds which are formed by the combination of carbon and hydrogen are called hydrocarbons.
Its examples are:
- Methane (CH4)
- Ethane (C2H6)
- Ethene (C2H4)
Differentiae between.
a. Saturated and unsaturated hydrocarbons
b. Alkanes and alkenes.
c. Alkanes and alkynes.
d. Propene and propyne.
a. Saturated and unsaturated hydrocarbons.
Saturated | Unsaturated |
The hydrocarbon in which carbon atoms are connected by single covalent bond is called saturated hydrocarbons. | The hydrocarbon in which carbon atoms are connected by multiple covalent bond are called unsaturated hydrocarbons. |
They are also called alkanes. | They are also called alkenes or alkynes. |
Alkanes | Alkenes |
It is connected by single covalent bond. | It is connected by multi-covalent bond. |
It is chemically less reactive. | It is chemically high reactive. |
It is saturated. | It is unsaturated. |
It is called paraffins. | It is called olefins. |
c. Alkanes and alkynes.
Alkanes | Alkynes |
It is connected by single covalent bond. | It is connected by triple covalent bond. |
It is saturated. | It is unsaturated. |
It is less reactive. | It is more reactive. |
Eg. Methane, Ethane, etc. | Eg. Methyne, Ethyne, etc. |
d. Propene and propyne.
Propene | Propyne |
It contains any two carbon atoms connected with double bond. | It contains any two carbon atoms connected with triple bond. |
It is chemically less reactive. | It is chemically high reactive |
It falls under alkene series. | It falls under alkyne series. |
