Question

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.

Answer 1

(D.) No, because polar covalent molecules have stronger intermolecular forces than nonpolar covalent molecules.

Step-by-step explanation:

In water molecules intermolecular hydrogen bonding occurs between hydrogen and highly electronegative elemnt oxygen that increases the intermolecular forces. Hence water has high boiling point.

Answer 2

D. No, because polar covalent molecules have stronger intermolecular forces than nonpolar covalent molecules.

Step-by-step explanation:

Hello,

Intermolecular forces are those which attract or repel molecules to, or from each other. In this case, since water is the involved molecule, it is known that it is a polar covalent one, as the difference between the electronegativities of oxygen and hydrogen is 1.24, in this manner, it is also known that the more polar the molecule is, the stronger its intermolecular forces are are they are tend to stick the molecules. In such a way, the answer is: D. No, because polar covalent molecules have stronger intermolecular forces than nonpolar covalent molecules.

Best regards.
