tetrahedral, trigonal pyramidal, 109.5 degrees, that determine the electron geometry, molecular geometry, and idealized bond angles for each molecule Large atoms such as Cl or Br.
It will cause bond angles to deviate from the ideal, and the presence of a multiple bond will cause a deviation as well owing to the increased electron density, so CH3Br should deviate from the idealized bond angle.
Electron geometry and molecular geometry are the arrangements of electrons or atoms in three-dimensional space around a central atom. This gives a molecule a specific shape and bond angles. Electron geometry helps us in determining the arrangement of various electron groups.
