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.

This video talks about the mechanism involved when a symmetrical alkyne is treated with a hydrogen halide. 00:00- Introduction 1:03-Reaction between ethyne and HBr 1:44- Why is there no resonance in case of a vinylic carbocation? 3:40- What happens if we have excess HBr? 4:42- How do we decide the major product?
