what are compound radicals? Give examples of a few radicals, along with their valencies.
Answers
Answer:
The compounds containing compound radicals give out compound radicals in their aqueous solutions. Examples of compounds containing compound radicals are as follows: Sulphuric acid (H2SO4): H2SO4 has compound radical SO2−4. Nitric acid (HNO3): HNO3 has compound radical NO−3.
Explanation:
The compounds containing compound radicals give out compound radicals in their aqueous solutions. Examples of compounds containing compound radicals are as follows: Sulphuric acid (H2SO4): H2SO4 has compound radical SO2−4. Nitric acid (HNO3): HNO3 has compound radical NO−3.
Answer:
The chemical species that contains a group of atoms which behave as a single unit in different compounds and have charge is known as a compound radical.
Explanation:
The chemical species that contains a group of atoms which behave as a single unit in different compounds and have unpaired valence electrons is known as a compound radical.
The breaking of a single covalent bond to leave an unpaired electron on both the species that are bonded by it lead to the formation of radicals.
The compound radicals can be of two types based on the charge they carry i.e. positive and negative.
The examples of compound radicals are as follows:
Nitrate (NO−3): The charge on the radical is −1. Thus, the valency of nitrate radical is 1.
Carbonate (CO2−3): The charge on the radical is −2. Thus, the valency of carbonate radical is 2.
Ammonium (NH+4): The charge on the radical is +1. Thus, the valency of ammonium radical is 1.
Sulphate (SO2−4): The charge on the radical is −2. Thus, the valency of sulphate radical is 2.
The compounds containing compound radicals give out compound radicals in their aqueous solutions. Examples of compounds containing compound radicals are as follows:
Sulphuric acid (H2SO4): H2SO4 has compound radical SO2−4.
Nitric acid (HNO3): HNO3 has compound radical NO−3.
Ammonium chloride (NH4Cl): NH4Cl has compound radical NH+4.
Consider nitric acid (HNO3). Nitric acid in its aqueous solution gives H+ and compound radical NO−3.
In the compound radical NO−3, we have to determine the valency of nitrogen and oxygen. This is known as the valency of parts.
In NO−3, the valency of nitrogen is 1 and the valency of oxygen is 2.
