Molecular Shape

Electron Domain Theory
● The shape of molecules depending on the room arrangement bonding pair (B)
and a pair of free electrons central atom (F) in the molecule. can be explained
the electron pair repulsion theory valence shell or VSEPR theory (Valence
Shell Electron Pair Repultion)
● molecule covalent electron pair are both B and F.
Because the electron pair have like charges, then between electrons pair. Repulsion
repulsion (B - B)
● The existence of repulsion causes the atoms bonded
form a certain space structures of a molecule thus
molecular shape is influenced by the amount of F and the B held on
the central atom.
● The shape of the molecule was determined by an electron pair bond
Examples of CH4 molecule has four B
