The organic compounds which having Carbon and Hydrogen are Hydrocarbons. They are classified into Straight chain or Acyclic hydrocarbons and Closed chain or Cyclic hydrocarbons. Straight chain hydrocarbons consist of Saturated and unsaturated hydrocarbons. They have specific nomenclature. Alkanes, Alkenes, and Alkynes are different hydrocarbons. Alkanes are the hydrocarbons having a single bond. Alkenes and Alkynes consist of double and Triple bonds respectively. There are various methods to prepare them. They have unique properties, uses, and reactions. Aromatic\u00a0 Hydrocarbons are those containing a benzene ring. Benzene has a special structure. Benzene is prepared in different ways. It reacts with different elements. Benzene undergoes a substitution reaction. So, this is a brief introduction to this chapter.
