Advantages And Disadvantages Of Diazonuim Salts
Introduction:
Diazonuim salts are unsaturated compounds which have a trible bond.
There was a scientist his name was Griess, this scientist gave Diazo name to diazonuim salts as he thought that two hydrogen atoms in the benzene ring will be replaced by two atoms of nitrogen.
Diazonuim salts divided into two types of salts:
Aromatic diazonuim salts and alephatic ( non– aromatic) diazonuim salts.
Non aromatic salts are less important than aromatic.
Under normal conditions, diazonuim salt is highly unstable.
Dizonuim salts have some properites such as shock–sensitive, decompose violenthly when heating and they can conduct electricity, for this reason they are considered one of the electrolyte compounds.
There are a lot of types of diazonuim ... Show more content on Helpwriting.net ...There is a type of reaction in which Nitrogen atom doesn't realese from the salt. This type of reaction is called reduction reaction, it done by using SNCl2 or Na2So3 to give hydrasin derivatives.
There is another type of diazonuim salts reactions which lead to the formation of azo dyes compounds, this reaction is done by adding some compounds to the salt such as, aromatic amines, compounds which have keton group in its structure like aceton, compounds which have OH group like phenol or naphthalen and hetrocyclic compounds in two steps:
– Step 1:
Formation of diazonuim salt.
– Step 2:
React diazonuim salt with coupling component which may be phenol or any type of aromatic amines so, a stable azo dye will be formed.
Azo dyes compounds have different structures as most of them contain only one azo group, but they may contain two or three or more azo groups.
Another methods of reactions
. SN1 reaction.
. sandmeyer reaction.
. gattermann reaction.
. baltz–schiemann reaction.
1– SN1 reaction:
On heating, diazonuim salts decompose into nitrogen and aryl cation which is could be attacked by any nucleophile due to its
