there are number of compounds having covalent bond and high melting point. Most common example is-diamond (Made of C)
Water is an example of a covalently bonded substance, consisting of one oxygen atom covalently bonded to each of two hydrogen atoms.
The given statement is not either true or false consistently. An ionic compound can contain atoms that are covalently bonded, as in sulfate and nitrate salts, but it need not contain any such covalently bonded atoms.

Water is an example of a covalently bonded substance, consisting of one oxygen atom covalently bonded to each of two hydrogen atoms.
If they are covalently bonded, it would be a molecule. If they are bonded by an ionic bond, they form an ionic compound.
An ion that contains a covalently bonded group of atoms is called a "polyatomic ion".
The given statement is not either true or false consistently. An ionic compound can contain atoms that are covalently bonded, as in sulfate and nitrate salts, but it need not contain any such covalently bonded atoms.
A Molecule
Oxygen is a pure substance. In nature, free oxygen exists as a molecule of two oxygen atoms covalently bonded, O2.
When two different atoms are covalently bonded, they form a molecular compound.
