What is the point group of H2?

The point group of H₂ (hydrogen molecule) is D∞h. This group indicates that H₂ has an infinite number of rotational symmetries around its bond axis (the axis connecting the two hydrogen atoms) and possesses horizontal symmetry. Additionally, it includes inversion symmetry, meaning the molecule remains unchanged when inverted through its center. Overall, the D∞h point group captures the symmetrical properties of the diatomic hydrogen molecule.
