Question
What are hydrocarbons? Explain with examples.
Solution
Hydrocarbon is a compound of hydrogen and carbon. Examples for hydrocarbons are methane (CH4), ethane (C2H6) and ethyne (C2H2). All these compounds are hydrocarbons as they are only made of hydrogen and carbon elements which is evident from their respective molecular formulae.
