Boron trifluoride is the inorganic compound with the formula BF 3. This pungent, colourless, ... The geometry of a molecule of BF 3 is trigonal planar.
Structure of boron trifluoride, an example of a molecule with trigonal planar geometry. In chemistry , trigonal planar is a molecular geometry model with one atom at the center and three atoms at the corners of an equilateral triangle , called peripheral atoms, all in one plane. [ 1 ]
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 geometrical parameters that determine the position of each atom.
However, the three hydrogen atoms are repelled by the electron lone pair in a way that the geometry is distorted to a trigonal pyramid (regular 3-sided pyramid) with bond angles of 107°. In contrast, boron trifluoride is flat, adopting a trigonal planar geometry because the boron does not have a lone pair of electrons.
In contrast, the extra stability of the 7p 1/2 electrons in tennessine are predicted to make TsF 3 trigonal planar, unlike the T-shaped geometry observed for IF 3 and predicted for AtF 3; [39] similarly, OgF 4 should have a tetrahedral geometry, while XeF 4 has a square planar geometry and RnF 4 is predicted to have the same.
The bond geometry change for a planar BF 3 molecule when bound to a metal. Many of the simplest Z-ligands are simple Lewis acids with electron-deficient center atoms such as BX 3, BH 3, BR 3, AlX 3, etc. While these molecules typically have trigonal planar geometry, when bonded to a metal center, they become tetrahedral.
