  2. VSEPR theory - Wikipedia

    en.wikipedia.org/wiki/VSEPR_theory

    Valence shell electron pair repulsion (VSEPR) theory (/ ˈ v ɛ s p ər, v ə ˈ s ɛ p ər / VESP-ər, [1]: 410 və-SEP-ər [2]) is a model used in chemistry to predict the geometry of individual molecules from the number of electron pairs surrounding their central atoms. [3]

  3. Bent molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Bent_molecular_geometry

    This geometry is almost always consistent with VSEPR theory, which usually explains non-collinearity of atoms with a presence of lone pairs. There are several variants of bending, where the most common is AX 2 E 2 where two covalent bonds and two lone pairs of the central atom (A) form a complete 8-electron shell .

  4. Formate - Wikipedia

    en.wikipedia.org/wiki/Formate

    Formate is a common C-1 source in living systems. It is formed from many precursors including choline, serine, and sarcosine.It provides a C-1 source in the biosynthesis of some nucleic acids.

  5. Linear molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Linear_molecular_geometry

    As described by the VSEPR model, the five valence electron pairs on the central atom form a trigonal bipyramid in which the three lone pairs occupy the less crowded equatorial positions and the two bonded atoms occupy the two axial positions at the opposite ends of an axis, forming a linear molecule.

  9. Bent's rule - Wikipedia

    en.wikipedia.org/wiki/Bent's_rule

    According to VSEPR theory, diethyl ether, methanol, water and oxygen difluoride should all have a bond angle of 109.5 o. [12] Using VSEPR theory, all these molecules should have the same bond angle because they have the same "bent" shape. [12] Yet, clearly the bond angles between all these molecules deviate from their ideal geometries in ...
