Yes, there are substances that exist without covalent bonds, such as ionic compounds where ions are held together by electrostatic attraction. Metallic bonds are also a type of bond that does not involve sharing of electrons. Additionally, hydrogen bonds, while not true covalent bonds, are intermolecular forces that can exist between molecules.

Covalent bonds
The two main types of chemical bonds are ionic and covalent.

Covalent Bonds
When electrons are shared, covalent bonds are formed. Covalent bonds are of two types, polar and non-polar. A complex type of covalent bonds are co-ordinate covalent bonds or dative bonds.
In cyclohexane molecule are the bonds are covalent (sigma) bonds.

The bonds in HONC molecules are typically covalent bonds. This means that the atoms share electrons to form a bond. These covalent bonds are strong and are the primary type of bond found in organic molecules.
Covalent bonding is a type of chemical bonding where atoms share electrons to achieve stability. In common substances like sugar and alcohol, covalent bonds hold the atoms together within the molecules, determining their structure and properties. For example, sugar molecules are formed by covalent bonds between carbon, hydrogen, and oxygen atoms, while alcohol molecules contain covalent bonds between carbon, hydrogen, and oxygen atoms as well.
The type of bonds that are present in table sugar are covalent bonds. Carbon, hydrogen, and oxygen comprise these covalent bonds.
