Why does the Moon lack water and other volatile compounds compared to the Earth?

Answer

Extreme heat from the impact vaporized these compounds

The formation of the Moon was a high-energy event involving a massive collision. The immense heat generated during this event was sufficient to vaporize water and other volatile compounds, preventing them from being incorporated into the Moon's structure as it solidified. This lack of water is a direct consequence of the catastrophic, high-temperature nature of the impact and aligns with observations and samples returned from the lunar surface.
