Verified step by step guidance

Understand the concept of covalent bonds: Covalent bonds involve the sharing of electron pairs between atoms. These bonds typically occur between non-metal atoms.

Identify the nature of each compound: Analyze the chemical composition of each given compound to determine if they involve covalent bonding.

Examine H2O (water): Water is composed of hydrogen and oxygen, both non-metals, forming covalent bonds by sharing electrons.

Examine CH4 (methane): Methane consists of carbon and hydrogen, both non-metals, forming covalent bonds through shared electrons.

Examine NaCl (sodium chloride): Sodium chloride is composed of sodium (a metal) and chlorine (a non-metal), forming ionic bonds through the transfer of electrons, not sharing, which is characteristic of covalent bonds.
