Determine the electron geometry, molecular geometry and polarity of tecl6.
Delvig [45]
The electron geometry of TeCl6 is octahedral, while the molecular geometry is octahedral, non polar. 
Octahedral geometry or six electron pairs is the basic geometry for a molecule containing a central atom with six pairs of electrons, such as TeCl6 or SF6. As we replace bonding pairs with non bonding pairs the molecular geometry changes to square pyramidal to square planar.
