Alkynes or Acetylene Acyclic unsaturated hydrocarbons containing a carbon-carbon triple bond are called alkynes or acetylenes. Their general formula is CnH2n-2 where n=2,3,4....etc. Structure of Triple bond Ethyne is the first member of alkynes series. Each carbon atom of ethyne is sp-hybridized and hence has two sp-hybridized orbitals. One sp-hybridized orbital … [Read more...] about Alkynes

Alkanes
Hydrocarbons are divided into two types: (1) Acyclic or open chain hydrocarbons (2) Cyclic or closed chain hydrocarbons Acyclic or open chain hydrocarbons These compounds contain open chains of carbon atom in their molecules. They are also called aliphatic hydrocarbons. These are further classified into following three categories : (1) Alkanes : An alkane has only … [Read more...] about Alkanes
Functional Or Characteristic Group
Hydrocarbons are the parent organic compounds. All other compounds are considered to have been derived from them by replacing one or more of their hydrogen atoms by some other more reactive atom or group. R—H --------> R—G -H and +G Each organic molecule consist of two parts i.e. R and G. The first part, i.e. R denotes the carbon -hydrogen framework of the … [Read more...] about Functional Or Characteristic Group
