2. Chemical Principles

Electron Deficiency: Boron has 3 valence electrons. B₂H₆ has a total of exactly 12 valence electrons (2x3 + 6x1).

Terminal Bonds: 8 electrons are used to form the 4 normal terminal B-H covalent bonds (2-center-2-electron).

Banana Bonds: This leaves only 4 electrons to bind the two Borons and two central Hydrogens together. The molecule solves this by forming two 3-center-2-electron (3c-2e) bonds. Each "banana" cloud contains only 2 electrons, shared across B-H-B.

Geometry: The 2 Boron atoms and 4 terminal H atoms lie exactly in the same plane. The 2 bridging H atoms lie perpendicularly above and below this plane.
