A hydrocarbon is an organic chemical compound composed exclusively of hydrogen and carbon atoms. Hydrocarbons occur naturally and form the basis of crude oil, natural gas, coal, and other important energy sources. In this unit of class 11 chemistry, we will learn in detail about nomenclature, isomerism, structure, preparation, physical & chemical properties of alkanes, alkenes, alkynes, & aromatic hydrocarbons. We will learn to explain different conformations of ethane (staggered & eclipsed). In aromatic hydrocarbon, we will also learn resonance structures, we will also think about how those reactions are occurring on a molecular level with reaction mechanisms- electrophilic substitution reactions of benzene (nitration, sulphonation, halogenation, Friedel craft's alkylation & acylation.

If the two substituents are on the same side of the double bond, the configuration of the bond is cis. If the two substituents are on opposite sides of the double bond, the configuration of the bond is trans.
