What are ambident nucleophiles explain with an examples – it has two different doner sites or group.
What are ambident nucleophiles?
Ambident nucleophiles contain more then one doner atom in the same doner groups. this mean, ambident nucleophiles has two negative sites (two doner groups).
The ambident nucleophiles is a nucleophiles that can react through two different negative sites are know as ambident nucleophiles.
Ambident nucleophiles is a type of nucleophilic attack in which nucleophilic attack from two or more different places in the molecules or ion. this mean, it has two nucleophilic sites through which they can attack. this is called ambident nucleophiles.
Nitrite ion ( NO2-) these are the best example of ambident ligands
lets know with example,
There are two different way to nitrite ion can attack,
- Through oxygen &
- Through nitrogen
1. When nitrite ion can attack through oxygen as a result alkyl nitrites is formed.
2. When nitrite ion can attack through nitrogen as a result nitro alkanes is formed.
Examples of ambident nucleophiles
Ambident nucleophiles is an anionic which has two nucleophilic sites (two negative sites) through which they can attack. as a results new product is formed. the another best example for ambident nucleophiles is,
Donate atleast one electron (e- pair) = Lewis base = Nucleophile.
this mean, If donate atleast one electron pair then it comes in Lewis base that is called nucleophile. you can understand with the help of examples.
F , Cl, Br, and CN have negative charge this mean, F is donate atleast one electron (one electron pair) this mean, F, Cl, Br, CN all atoms is nucleophile.
In case of neutral, accepting electron to complete octat. so, we can say that this is nucleophile.
H – O – H
R – O – H
R – O – R
+ vely charge
Donating Electrophile, due to this, it is called nucleophile.
NH3 – NH3
+ vely charge
Here, atoms have positive charge, this mean, it required electron and it is accept electron to complete octat. If atom required to accept atleast one electron pair, this is called Electrophile.
In this case, both have accepting electrons. so we can say that, it is considered as a electrophile.
In this case, accepting electrons, due to this, this is called Electrophile.
