This drawing is linear—a straight line. Systematic investigation of the Raman spectra upon heating the crystalline forms of BeCl revealed two different solid phase transitions at 350 and 405 °C. Lewis structures show the two-dimensional distribution of atoms and electrons. There is a simple procedure that allows us to predict overall geometry is the VSEPR , V alence S hell E lectron P air R epulsion. The “best” Lewis structure is one that has the fewest formal charges — the top structure. In BeCl 2, the dipole moment of one chlorine cancels out the dipole moment of other chlorine and hence the net dipole moment is. It is a good thing for us that this is so, since this imparts a degree of polarity to the water molecule. Double and triple bonds count as ONE REGION OF HIGH ELECTRON DENSITY. Diatomics for instance are very highly covalent since it is a bond with two atoms of the same element (which then have the same electronegativity). BeCl2 is covalent, with Be having a share of 4 electrons. So you can see, that one Lewis structure is not enough to actually describe the bonding in that molecule well, but as a first approximation, the left hand structure above should be sufficient.
