In a covalent bond the electrons are shared between atoms.
Covalent compounds
Covalently bonded compounds are characterized by a molecular formula, because such compounds exist in the form of discrete molecules, all of the atoms of which move together as kinetic-molecular units. Ionically bonded compounds do not have molecules in this sense: Their compounds are made up of at least two kinds of ions, one positive and the other negative, and the ions in these compounds can move separately as kinetic-molecular units: If a positive ion is separated from the particular negative ion with which it was most closely associated initially in a fluid mixture, usually a solution in an ionizing solvent, of both kinds of ions, another negative ion with the same properties is always close by.
Covalent Bonds
Simple molecular compounds have discrete molecules held together by weak intermolecular forces, while giant molecular compounds have repeating units bonded together by strong covalent bonds. Simple molecular compounds typically have low melting and boiling points and are often gases or liquids at room temperature, while giant molecular compounds tend to have high melting and boiling points and are usually solids at room temperature.
The same atoms bonded together are elements. Different atoms bonded together are compounds. Oxygen gas, O2, is an element composed of molecules of two oxygen atoms covalently bonded. Water, H2O is a molecular compound composed of two hydrogen and one oxygen atoms covalently bonded. Common table salt, NaCl, is an ionic compound composed of sodium and chloride ions ionically bonded.

The binary molecular compound of CCl4 is carbon tetrachloride. It is composed of one carbon atom and four chlorine atoms covalently bonded together.
Sucrose is a molecular compound. It is composed of carbon, hydrogen, and oxygen atoms bonded together covalently to form molecules. It is not made up of ions like ionic compounds.
Calcium acetate and potassium hydroxide are molecular compounds as they are composed of nonmetal elements. Nitrogen monoxide is also a molecular compound, consisting of nitrogen and oxygen elements bonded together covalently.
Se4S4 is a molecular compound. It consists of selenium and sulfur atoms bonded together covalently to form a molecular structure.
Covalent compounds
Molecular compounds are composed of all types of elements. I think the answer you're going for is what type of BONDS are molecular compounds composed of. In which case, the answer would be covalant, however this can vary between polar and nonpolar covalant, that's what a molecular compound is made of, otherwise it's an ionic compound.

NO is a molecular compound, not an ionic compound. It is made up of individual atoms of nitrogen and oxygen that are covalently bonded together.
Nitrogen oxide is a molecular compound, not an ionic compound. It is composed of nitrogen and oxygen atoms bonded together covalently.
