3 (pi) bonds
The effect of lone pairs of electrons on molecular geometry is
to push other atoms closer together because lone pairs are
localized on only one nucleus, so they spread out more.
to allow the other atoms to be further apart because lone pairs
take up less space than bonding pairs.
to create an aysmmetical distribution of the electrons within
the atom, thus creating a polar molecule by creating dipoles.
to help to create resonance structures through the formation of
pi bonds.
Why can a molecule with the structure of NBr5 not exist?
Nitrogen only has two energy levels and is thus unable to expand its octet.
Bromine is much larger than nitrogen and cannot be a terminal atom in this molecule
It is impossible to complete the octets for all six atoms using only valence electrons.
Nitrogen does not have a low enough electronegativity to be the central atom of this molecule.
The molecule that uses sp3d hybrid orbital on the central atom is
BCl3
NCl3
ICl3
PCl3
