Question

Write the examples of basic radicals.

Answer 1

Hint:The radicals which are not positively charged and are negatively charged are known as basic radicals. These basic radicals are formed when the hydroxide ions \[O{H^ - }\] . The radicals are of two types – acidic radicals and basic radicals.

Complete answer:
A radical is an atom or group of atoms of an equivalent or of various elements that behave as one unit with a positive or charge. A radical could also be a basic radical (having a positive charge, that is, cation). A radical could also be an acidic radical (having a negative charge, that is, anion). They can form chemical formulae by using combining power because they have their own combining power.
The radicals are of two types –
Acidic radicals: The radicals which are negatively charged are known as acidic radicals. These types of radicals are formed by the removal of hydrogen ${H^ + }$. This makes the compound acidic radical. For example - ${H_2}S{O_4}$ loses one ${H^ + }$ to form $HSO_4^ - $ ion.
Basic radicals: These types of radicals can be defined as the positively charged radicals. When the hydroxide ion $O{H^ - }$ is removed from the compound then the resulting ion becomes the basic radical. For example - $KOH$ loses $O{H^ - }$ ion and becomes ${K^ + }$ ion.
Some of the other examples of basic radicals are - $N{a^ + },F{e^{2 + }},A{g^ + },A{l^{3 + }},C{r^{3 + }},A{u^{3 + }},C{o^{2 + }},N{i^{2 + }},H{g^{2 + }},S{n^{2 + }}$ etc.

All the radicals written above are positively charged therefore, these all are basic radicals.

Note: A radical is an atom, molecule, or ion that has an unpaired valence electron. With some exceptions, these odd electrons create radicals highly chemically reactive. several radicals spontaneously dimerize.
