To determine which of these compounds are formed by covalent bonds, we need to understand what covalent bonds are. Covalent bonds are formed when two atoms share electrons, typically nonmetals.

1. CH: This is a covalent compound. Carbon (C) and Hydrogen (H) are both nonmetals, and they form covalent bonds by sharing electrons.

2. NaCl: This is an ionic compound. Sodium (Na) is a metal and Chlorine (Cl) is a nonmetal. Metals and nonmetals typically form ionic bonds, where the metal loses electrons to become a positively charged cation and the nonmetal accepts those electrons to become a negatively charged anion.

3. MgO: This is also an ionic compound. Magnesium (Mg) is a metal and Oxygen (O) is a nonmetal. As with NaCl, they form an ionic bond.

4. CaO: This is another ionic compound. Calcium (Ca) is a metal and Oxygen (O) is a nonmetal. They form an ionic bond.

So, out of the compounds listed, only CH is formed by covalent bonds.
