  • Cartoon of the approach of a p-type highest occupied molecular orbital of a nucleophile such as chloride ion , and the lowest unoccupied molecular orbital of the trigonal center of an electrophilic carbonyl of formaldehyde . View is nearly side on, and the developing out-of-plane distortion of the carbonyl carbon atom is omitted for simplicity. (en)
  • Shown is nucleophilic attack by the charged nucleophile , hydride anion, on the unsaturated trigonal center of the aldehyde electrophile, formaldehyde . The value computed as optimal for this system, 107°, is indicated, and is representative of the obtuse values observed in most experimental chemical systems. (en)
