Question

Give examples of positive radicals?

Answer 1

Hint: The charge which is present on an atom or molecule is going to be called as radical. The radicals may be positive or negative. The type of charge or radical on an atom or molecule is going to depend on the atom whether it accepts or donates electrons.

Complete answer: - In the question it is asked to write the example for positive radicals.
- We must remember that the radicals are usually unstable and highly reactive. They are short lived species. We saw that a free radical species which carries a charge is called a radical ion.
Radical ions are of two types, positive radical ions and negative radical ions.
- We know that cationic radical species possess low stability and we can see them in the mass spectrometry.
- In mass spectroscopy the chemical or compound first going to be converted into radical ion with the help of ionization chamber.
- Then the ionization chamber makes the compound into positively charged radical ions and they are going to be detected by the detector.
- Maybe the positive radicals contain a charge of +1, +2 and etc.
- Some of the examples of positive radicals are $N{{a}^{+}},F{{e}^{2+}},A{{l}^{3+}},A{{g}^{+}},C{{r}^{3+}},A{{u}^{3+}}$ .

Note: We are not supposed to confuse radicals and ions. An ion contains a different number of electrons when compared to protons. One of the most common radical cations in organic chemistry is methyl cation and we can see radical cations are commonly seen in conducting polymers.
