What is the molecular geometry of SeCl4?
What are the 3 Imfs?
What is the weakest type of attractive force between particles?
In a water molecule (H2O), the oxygen nucleus with +8 charges attracts electrons better than the hydrogen nucleus with its +1 charge. The hydrogen atoms are not only covalently attached to their oxygen atoms but also attracted towards other nearby oxygen atoms. This attraction is the basis of the ‘hydrogen’ bonds.
Phosphine is an example of a polar molecule with non-polar bonds. It has the formula PH3. The phosphorus is bonded to three hydrogen atoms and has a lone pair of electrons.
trigonal pyramidal
What shape would Ph3 have?
SeCl4 has often been used as an example for teaching VSEPR rules of hypervalent molecules. As such, one would predict four bonds but five electron groups giving rise to a seesaw geometry.
