Classes Of Functional Groups
Organic Chemistry deals mostly with carbon and hydrogens, also called hydrocarbons, but those groups which replace hydrogen and bonds with carbon to give a characteristic nature, unique of their own, to the hydrocarbon they are attached to, are called functional groups. All the compounds belonging to a functional group undergo reactions in a similar pattern and are known to have similar physical and chemical properties.
Characteristics Of Functional Groups
In organic chemistry, we encounter a number of special substituent groups which are attached to the hydrocarbon backbone. These groups impart certain characteristics to the molecule of which it is a part of and thus, become the highlight of that particular molecule.
IUPAC Nomenclature
In Chemistry, IUPAC stands for International Union of Pure and Applied Chemistry which suggested a systematic naming approach for the organic and inorganic compounds, as in the beginning stage of nomenclature one single chemical compound was named in many ways by which lead to confusion. The need for this approach aroused as the number of chemical compounds newly discovered were increasing (approximately 32 million compounds) and the basic concept of nomenclature i.e. the trivial nomenclature and the derived system of nomenclature failed to overcome the challenge. It is an important task to name a chemical compound systematically and unambiguously which reduces lots of confusion about the newly reported compounds.
how do you name this? thank you !!
In this question, name of the given structure is to be determined.
The given structure is :
Nomenclature of organic compounds :
The nomenclature of any organic compound is assigned by some set of rule which are given by IUPAC (International Union of Pure and Applied Chemistry).
The given structure is :
The naming for the structure is written in the form of prefix-base name-suffix.
Firstly, this structure has 4 carbon atoms and the carbon 1 is alkene. The base name for the 4 carbon atoms chain is -but- and suffix for the alkene is -ene.
Numbering assign to the carbon atoms of this structure should be starting from the double bonded carbon atom.
Since, alkene is attached with carbon number 1, so, the prefix will be 1 .
Thus, the name of the given structure is 1-butene or it may be written as but-1-ene.
