Question

Water molecules have a polarity, which allows them to be electrically attracted to other water molecules and other polar molecules by weak chemical bonds known as _____.
a. Van der Waals interactions
b. ionic bonds
c. hydrogen bonds
d. nonpolar covalent bonds
e. polar covalent bonds

Answer 1

Answer: Option (e) is the correct answer.

Explanation:

Atomic number of hydrogen is 1 and atomic number of oxygen is 8 (electronic distribution is 2, 6). When both hydrogen and oxygen atoms chemically combine with each other then sharing of electrons take place between the two atoms.

As a result, a covalent bond is formed. But due to the difference in electronegativity of both hydrogen and oxygen atom there occurs a partial positive and partial negative charge on hydrogen and oxygen atoms.

Hence, water is able to form polar covalent bonds with other polar molecules.

Thus, we can conclude that water molecules have a polarity, which allows them to be electrically attracted to other water molecules and other polar molecules by weak chemical bonds known as polar covalent bonds.
