The 4 pages that link to Bent molecular geometry, each with the reason it gives.

• Tetrahedral molecular geometryCompared with: Two lone pairs can leave only two bonded atoms in a tetrahedral electron-domain arrangement.

• Trigonal planar molecular geometryCompared with: A lone pair can leave three electron domains but only two bonded atoms, producing a bent shape.

• Linear molecular geometryCompared with: A central atom's lone pairs can produce a bent shape instead of a linear one.
