O2 (oxygen gas)
Verified step by step guidance1
Identify the types of intramolecular forces present in each molecule or compound. Intramolecular forces are the forces that hold atoms together within a molecule or compound, such as covalent bonds or ionic bonds.
For CH4 (methane), recognize that it is a covalent molecule with nonpolar covalent bonds between carbon and hydrogen atoms.
For CO2 (carbon dioxide), note that it is a linear molecule with polar covalent bonds, but the molecule is overall nonpolar due to its symmetry.
For O2 (oxygen gas), understand that it is a diatomic molecule with a nonpolar covalent bond between the two oxygen atoms.
For NaCl (sodium chloride), identify that it is an ionic compound composed of positively charged sodium ions (Na⁺) and negatively charged chloride ions (Cl⁻), which are held together by strong ionic bonds, a type of intramolecular force stronger than covalent bonds in these molecules.
