Chemistry: A Molecular Approach (3rd Edition)

Electron geometry: tetrahedral Molecular geometry: tetrahedral Idealized bond angle: $109.5^{\circ}$ Deviation from idealized bond angle : no
$CF_4$ has 4 covalent bondsand no lone pairs on the C atom. Its electron geometry is tetrahedral. Its molecular geometry is also tetrahedral since C atom is bonded to 4 F atoms. Its idealized bond angle is that of the tetrahedral geometry, $109.5^{\circ}$. There is no deviation from the idealized bond angle.
