The Lewis diagram for CSe2 is: Se=C= =S Recall that for predicting geometry, double and triple bonds count as only one electron pair. Here in CO2, both Oxygen atoms form sigma bonds with the central carbon atom and complete their octet. Step 2: The number of valence electrons further required to stabilize the molecule It is 8 as four are required by the carbon atom and two are required by each selenium atom. Here in the CS2 molecule the number of sigma bonds on the central atom is two and there are no lone pairs on the central atom as its octet is complete by sharing the valence electrons. The electron-domain geometry around O is therefore tetrahedral, which gives an ideal angle of 109.5. 4 Spectral Information Expand this section.
