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.

(2) Number the carbons, ensuring the double bond gets the lowest possible number. (3) Include the double bond location as a prefix to the root name. (4) Add any substituents as prefixes, in alphabetical order if needed. (5) Use the "-ene" suffix to indicate the molecule is an alkene.
