How are the 9 E) Answer the following questions : 3 i) Define : Hydrocarbon. ii) Types of hydracarbon.
Answers
Answer:
Explanation:
A compound made up of hydrogen and carbon only is called a hydrocarbon. (Hydrogen+Carbon=Hydrocarbon). For example : Methane (CH

), all are hydrocarbons as they are made up of only two elements: carbon and hydrogen.
(b) Saturated Hydrocarbons: These are the ones in which the carbon atoms are connected by only single bonds. They are also known as alkanes.
Example: Methane (CH

Unsaturated Hydrocarbons: These are the ones in which two carbon atoms are connected by a double bond or a triple bond.
Example: Ethene (C
