Question

question 3 (1 point) a polar covalent bond ______.

a shares electrons equally between atoms

b is found only in molecules containing oxygen

c is found only in h2o

d results from the unequal sharing of electrons

Explanation:

• Option a: A non - polar covalent bond shares electrons equally between atoms, so a is incorrect.
• Option b: Polar covalent bonds can be found in many molecules, not just those containing oxygen (e.g., HCl has a polar covalent bond), so b is incorrect.
• Option c: Polar covalent bonds are present in many compounds other than H₂O (e.g., NH₃, HCl), so c is incorrect.
• Option d: By definition, a polar covalent bond results from the unequal sharing of electrons between atoms due to differences in electronegativity.

Answer:

d. results from the unequal sharing of electrons
