Bobby found that water has a high boiling point and concluded this was because water has weak intermolecular forces. based on the data, is bobby’s conclusion correct? a. yes, because polar covalent molecules have weaker intramolecular forces than nonpolar covalent molecules. b. yes, because polar covalent molecules have weaker intermolecular forces than nonpolar covalent molecules. c. no, because polar covalent molecules have stronger intramolecular forces than nonpolar covalent molecules. d. no, because polar covalent molecules have stronger intermolecular forces than nonpolar covalent molecules.
