Question

1. what type of bond exist between a hydrogen and an oxygen atom? (1 point) *

polar covalent
nonpolar covalent
ionic

Explanation:

To determine the bond between H and O:

1. Polar Covalent: Occurs when atoms share electrons unequally (due to electronegativity difference). O (3.5) and H (2.1) have a significant electronegativity difference, so electrons are pulled more toward O, creating a polar bond.
2. Nonpolar Covalent: Requires equal electron sharing (e.g., same atoms like O - O), which is not the case here.
3. Ionic: Involves complete electron transfer (e.g., metal - nonmetal), but H and O are both nonmetals and share electrons, not transfer.

Thus, the bond is polar covalent.

Answer:

A. Polar covalent
