A hydrocarbon is an organic compound that consists entirely of hydrogen and carbon. Some examples coal, petroleum and natural gas and paraffin.
Petroleum oil and all its by-products are hydrocarbons.
It is done by the process of Hydrogenation. Example:- C2H4 + H2 ---------> C2H6 Thus, ethene undergoes hydrogenation to form ethane
wax is a hydocarbon( a compound composed of hydrogen and carbon only).all hydrocarbons give carbon-dioxide and oxygen on combustion cxHy + O2 ---> CO2 + H2
In organic chemistry, a hydrocarbon is a compound consisting of only carbon and hydrogen atoms. There are different types of hydrocarbons, such as saturated hydrocarbons, which include alkanes (e.g.- methane), unsaturated hydrocarbons, which include alkenes and alkynes (e.g.- ethylene and ethyne), cycloalkanes (e.g. - cyclopropane), and arenes, also known as aromatic hydrocarbons (e.g. - benzene).
