Concept Introduction:
Octet Rule:
The octet rule states that the noble gas electron configuration is attained by the element, when the element either loses or gains or shares its atoms. The formulas for the compounds that contain specific elements can be predicted with the help of Octet rule. The octet rule holds good for those compounds that are made of elements present in second period and hence the important study on organic compounds that mainly consists of Carbon, Nitrogen and Oxygen atoms can be done with the help of Octet rule. The loss gain or sharing electrons of particular atom is dependent on properties of atoms that are determined by the number of subatomic particles inside in the atom.
Resonance:
Resonance is a method to relating to describe about delocalized electrons inside certain molecules or polyatomic ions where the Lewis structure can’t be expressed. A molecule or ion containing delocalized electrons can be represented by using several similar structures such structures are called as resonance structures or canonical structures.
The delocalization of electron lowers the potential energy of the substance and making it more stable than any of the contributing structures. The variation in the potential energy of the actual structure and that of resemblance structure with lowest potential energy is known as resonance energy or delocalization energy.

Chemistry: Atoms First
- Write all resonance structures of chlorobenzene, C6H5Cl, a molecule with the same cyclic structure as benzene. In all structures, keep the CCl bond as a single bond. Which resonance structures are the most important?arrow_forwardDraw resonance structures for each of these ions: NSO− and SNO−. (The atoms are bonded in the order given in each case, that is, S is the central atom in NSO−.) Use formal charges to determine which ion is likely to be more stable. Explain why the two ions cannot be considered resonance structures of each other.arrow_forwardDraw resonance formulas of the phosphoric acid molecule, (HO)3PO. Obtain formal charges for the atoms in these resonance formulas. From this result, which resonance formula would you expect to most closely approximate the actual electron distribution?arrow_forward
- Three resonance forms can be drawn for the molecule N2O. Which resonance form is likely to more closely resemble the structure of this molecule? (a) (b) (c)arrow_forwardThree known isomers exist of N2CO, with the atoms in these sequences: NOCN; ONNC; and ONCN. Write resonance structures for each isomer and use formal charge to predict which isomer is the most stable.arrow_forwardConsider the pyrosulfate ion, S2O72-. It has no sulfur–sulfur nor oxygen–oxygen bonds. (a) Write a Lewis structure for the pyrosulfate ion using only single bonds. (b) What is the formal charge on the sulfur atoms for the Lewis structure you drew in part (a)? (c) Write another Lewis structure using six bonds and two O—S bonds. (d) What is the formal charge on each atom for the structure you drew in part (c)?arrow_forward
