what is the generally difference btw nitrile,nitride , sulphide,sulphite what is the general difference and where they are actually used there is some confusion plz clear my doubt
The nitrile, nitride, sulphide and sulphite groups are all different groups. However, all of these groups are actually anions. The nitrile group is polyatomic anion with a charge of -1 and written as CN-. It is also known as the cyano group. Example KCN is known as potassium cyanide. It is also a functional group encountered commonly in organic chemistry. Thus the compounds with the general formula RCN belong to the family of cyanides. For example CH3CN would be called methyl cyanide or ethanenitrile, CH3CH2CN would be called ethyl cyanide or propanenitrile.
The nitride group is N3-. It is group found in compounds of nitrogen in which the nitrogen atom carries an oxidation state of -3. It is found in ionic compounds like Mg3N2.
The sulphide group is S2- (sulphur atom carrying -2 charge). It is found in compounds like sodium sulphide (Na2S), Hydrogen sulphide (H2S).
The sulphite ion is SO32- (complex ion composed of 4 atoms carrying a charge of -2). Examples of compounds containing this group include sodium sulphite (Na2SO3), potassium sulphite (K2SO3).
Note that while the nitrile group is found in both organic as well as inorganic compounds, the nitride, sulphide and sulphite groups are more common in inorganic compounds than organic compounds.
