What is the structure of cyano compound with 6 carbon atom and their IUPAC naming?


What is the structure of cyano compound with 6 carbon atom and their IUPAC naming?



Cyano compounds are those compounds in which alkyl groups are attached with the carbon atom of – CN functional group. Cyano compounds are also known as nitrile compounds.

The general formula of cyano compound is CnH2n+1–CN. Depending on the number of cyano group, cyano compounds may be mono cyano,dicyano,tricyano etc.


structure of cyano compound with 6 carbon atom and their IUPAC naming

In case of IUPAC nomenclature of cyano compounds, the carbon atom of cyano group must be considered. That is, we select long chain including cyano group and then numbering the carbon atom.

According to IUPAC rules, the cyano compounds are named as,

Root alkane + nitrile  = alkane nitrile

The carbon atom of root alkene must be equal to the carbon atom present in the long chain of the concern cyano compound.
For example, butane nitrile, pentane nitrile, hexane nitrile etc.


If the cyano compounds contain branch chain,then the naming of the branch chain with their position in the alphabetic order first and then naming of the root chain.

Again, if a cyano compound contain more than one cyano group, then in nomenclature, the sequence is, position of the cyano group + root alkane name + number of cyanogroup [ di, tri, tetra etc ] + carbonitrile.

 For example,4-amino 3-methyl hexane nitrile.

The structure of some cyano compounds with 6 carbon atom and their IUPAC nomenclature are shown below.
