  2. Bent molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Bent_molecular_geometry

    Water (H 2 O) is an example of a bent molecule, as well as its analogues. The bond angle between the two hydrogen atoms is approximately 104.45°. [ 1 ] Nonlinear geometry is commonly observed for other triatomic molecules and ions containing only main group elements, prominent examples being nitrogen dioxide (NO 2 ), sulfur dichloride (SCl 2 ...

  3. Bent's rule - Wikipedia

    en.wikipedia.org/wiki/Bent's_rule

    Bent's rule accuracy and precision in predicting the geometry of real-world molecules continues to demonstrate its credibility. [ 5 ] [ 15 ] Beyond bond angle prediction, Bent's rule has some significant applications and is of considerable interest to chemists.

  4. Bent bond - Wikipedia

    en.wikipedia.org/wiki/Bent_bond

    The term itself is a general representation of electron density or configuration resembling a similar "bent" structure within small ring molecules, such as cyclopropane (C 3 H 6) or as a representation of double or triple bonds within a compound that is an alternative to the sigma and pi bond model.

  5. Molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Molecular_geometry

    Some common shapes of simple molecules include: Linear: In a linear model, atoms are connected in a straight line. The bond angles are set at 180°. For example, carbon dioxide and nitric oxide have a linear molecular shape. Trigonal planar: Molecules with the trigonal planar shape are somewhat triangular and in one plane (flat). Consequently ...

  6. VSEPR theory - Wikipedia

    en.wikipedia.org/wiki/VSEPR_theory

    VSEPR theory is used to predict the arrangement of electron pairs around central atoms in molecules, especially simple and symmetric molecules. A central atom is defined in this theory as an atom which is bonded to two or more other atoms, while a terminal atom is bonded to only one other atom.

  7. Walsh diagram - Wikipedia

    en.wikipedia.org/wiki/Walsh_diagram

    [1] [2] By plotting the change in molecular orbital levels of a molecule as a function of geometrical change, Walsh diagrams explain why molecules are more stable in certain spatial configurations (e.g. why water adopts a bent conformation). [3]

    Researchers from Mass General Brigham, a health care system in Boston, Massachusetts, shared with Fox News Digital some of the scientific developments and breakthroughs they expect to see in 2025.

  9. Tetrahedral molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Tetrahedral_molecular_geometry

    In the gas phase, a single water molecule has an oxygen atom surrounded by two hydrogens and two lone pairs, and the H 2 O geometry is simply described as bent without considering the nonbonding lone pairs. [citation needed] However, in liquid water or in ice, the lone pairs form hydrogen bonds with neighboring water molecules. The most common ...
