Organic Chemistry Functional Groups Cheat Sheet - print this guide for a handy reference to the common groups you will come across during IUPAC naming and advanced reactions:
The unsaturated hydrocarbons those are contain at least one carbon – carbon double bond is called alkene or olefin. The general formula of alkenes or olefins compound is, Cn H2n. Where, n = 2 , 3, 4, 5……….etc. 1 to 20 IUPAC name of alkenes What is the IUPAC name of four alkenes hydrocarbon ?
Functional groups are structural units that determine the chemical reactivity of a molecule under a given set of conditions. Organic compounds are classified into several major categories based on the functional groups they contain. In the systematic names of organic compounds, numbers indicate the positions of functional groups in the basic hydrocarbon framework.
