How is hydrogen bond different from a covalent bond and draw a diagram of water molecules labeling the hydrogen bond and covalent bond?

A hydrogen bond is a weak attraction between a hydrogen atom bonded to an electronegative atom (like oxygen) and another electronegative atom, while a covalent bond is a strong bond formed when two atoms share electrons. In water (H₂O), the oxygen atom forms covalent bonds with two hydrogen atoms by sharing electrons. The hydrogen bonds occur between water molecules, allowing them to attract each other.

Below is a simple representation of the structure of water molecules, labeling the bonds:

<code>      O
/ \ H   H |   |  (Hydrogen bond) H---O---H
</code>

In this diagram, the lines connecting H and O represent covalent bonds, while the dashed lines between different water molecules represent hydrogen bonds.
