Step-by-step explanation:
- A compound whose atoms are chemically combined together through sharing of electrons are known as covalent compound.
A covalent compound is generally formed by non-metals.
For example, in HBr compound both hydrogen and bromine are non-metals. Whereas in
compound also both carbon and oxygen atoms are non-metals.
- An ionic compound is defined as a compound formed due to transfer of electrons from one atom to another.
For example, NaCl and MgO are both ionic compounds.
An ionic compound is always formed between a metal and a non-metal.
Thus, we acn conclude that out of the given options HBr and
chemical formulas shows a covalent compound.
