Molecular shapes are predicted using the valence shell electron pair . These bonds will account for 8 of the 16 valence electrons of the molecule. The overall shape is that of a tetrahedron (i.e., a pyramid with all faces being equilateral triangles, or nearly so). The three lone pairs are in the equatorial positions, leaving the Cl and I in a linear molecular shape. If ans comes 2, it will be (sp), 3(sp2), 4(sp3/dsp2), 5(dsp3), 6(d2sp3. Follow all the aforementioned steps to draw the final Lewis structure of the carbon diselenide molecule: The valence electrons tend to stabilize their octet by allowing a maximum of eight of them within the outermost shell. And because this we can say, OK, so this is one electron pair. It can be studied with the help of the Valence Bond Theory (VBT) which says that atomic orbitals mix and intermix to produce new hybrid orbitals that can pair valence electrons to form new chemical bonds. Draw the Lewis Structure of CSe2 2. Lewis structures, also known as electron-dot or electron-dot diagrams, are diagrams showing the bonding between a molecule's atoms and the lone pairs of electrons that may occur in the molecule. 1.
