Bond angles are the angles between two adjacent bonds in a molecule. Learn how to calculate bond angles using the VSEPR theory and how lone pairs affect them.
Bond angle can be defined as the angle formed between two covalent bonds that originate from the same atom. An illustration detailing the bond angle in a water molecule (104.5 o C) is provided below. The geometric angle between any two adjacent covalent bonds is called a bond angle. This bond parameter provides insight into the molecular ...

Molecular geometry. Geometry of the water molecule with values for O-H bond length and for H-O-H bond angle between two bonds. Molecular geometry is the three-dimensional arrangement of the atoms that constitute a molecule. It includes the general shape of the molecule as well as bond lengths, bond angles, torsional angles and any other ...
- Valence-Shell Electron-Pair Repulsion Theory. Now that we have a background in the Lewis electron dot structure we can use it to locate the the valence electrons of the center atom.
- VSEPR Notation. As stated above, molecular geometry and electron-group geometry are the same when there are no lone pairs. The VSEPR notation for these molecules are AX"A" represents the central atom and n represents the number of bonds with the central atom.
- Molecules with More than One Central Atom. The VSEPR theory not only applies to one central atom, but it applies to molecules with more than one central atom.
- Bond Angles. Bond angles also contribute to the shape of a molecule. Bond angles are the angles between adjacent lines representing bonds. The bond angle can help differentiate between linear, trigonal planar, tetraheral, trigonal-bipyramidal, and octahedral.
May 18, 2021 · A bond angle is the angle between any two bonds that include a common atom, usually measured in degrees. A bond distance (or bond length) is the distance between the nuclei of two bonded atoms along the straight line joining the nuclei. Bond distances are measured in Ångstroms (1 Å = 10 –10 m) or picometers (1 pm = 10 –12 m, 100 pm = 1 Å).
Feb 28, 2022 · Gamini Gunawardena. Utah Valley University. A bond angle is the angle between two bonds originating from the same atom in a covalent species. eg. 1: eg. 2: Geometrically, a bond angle is an angle between two converging lines. eg: see also dihedral angle.
