Other structures can be written, but they will be destabilized by reduced bonding and/or charge separation. This theory is based on the steric number of the central atom and the valence electrons of the compound. ; You might think you've got the correct Lewis structure for ClO 3-at first. This means that a) two carbon-to-oxygen bonds are single bonds; the third is a double bond. (iii) Due to resonance the two oxygen atoms have partial double bond character and thus have same bond length i.e. Ammonium has no #pi# bonds at all, and so it cannot have any resonance. Sketch The Lewis Dot Structures For Each. Expert Answer 100% (8 ratings) Previous question Next question Hence the hybridization of the central atom Xe is sp3d.

(b) Draw the structures of the following molecules: (i) XeF 2 (ii) H 2 S 2 O 8 Answer: (a) (i) It is less soluble in blood than nitrogen and does not cause bends (pain) in body under the pressure of water. The Carbonate (\(CO_3^{2−} \)) Ion Like ozone, the electronic structure of the carbonate ion cannot be described by a single Lewis electron structure. Ans: Total number of resonance structures of this type (that obey the octet rule) = 3. This structure helps in understanding the charges on the molecules of the compound. In general, molecules with multiple resonance structures will be more stable than one with fewer and some resonance structures … Question: Does The Molecule SF6 Have Resonance Structures? Here, A would be the central carbon, X would be the number of atoms attached to that central carbon (In HCN, there are two – Hydrogen and Nitrogen) and N would be the number of lone pair electrons or nonbonding electron pairs.
