Consider the following incomplete structures. On your rough sheet, complete their correct Lewis structures (including minimizing formal charge) by adding electrons/bonds where necessary. Which statement below is true of the completed Lewis structures? Hint: Consider the potential for multiple bonds on the molecules and be sure to account for all valence electrons. The BrOCI, exhibits both nonzero formal charges and resonance frybrids, while the NOCI, exhibits resonance hybrids but no nonzers formal charges At least one atom in each molecule exhibits nonzero formal charges, and the molecules have no resonance hybrids O The NOO," exhibits nonzero formal charges but no resonance hybrids, while the BOC, exhibits both nonzero formal charges and resonance hybrid O The BrOC" exhibits nonzero formal charges but no resonance hybridh. While the NOO," exhibits resonance hybrids but no nonzero formal charges The NOCI, exhibits both nonzero formal charges and resonance hybrids, while the BOC, exhibits nonzero formal charges but no resonance hybrids O The NOO," exhibits both nonzero formal charges and resonance hybrids, while the BOC, exhibits resonance hybrids but no nonzero formal charges O None of these
Formal Charges
Formal charges have an important role in organic chemistry since this concept helps us to know whether an atom in a molecule is neutral/bears a positive or negative charge. Even if some molecules are neutral, the atoms within that molecule need not be neutral atoms.
Polarity Of Water
In simple chemical terms, polarity refers to the separation of charges in a chemical species leading into formation of two polar ends which are positively charged end and negatively charged end. Polarity in any molecule occurs due to the differences in the electronegativities of the bonded atoms. Water, as we all know has two hydrogen atoms bonded to an oxygen atom. As oxygen is more electronegative than hydrogen thus, there exists polarity in the bonds which is why water is known as a polar solvent.
Valence Bond Theory Vbt
Valence bond theory (VBT) in simple terms explains how individual atomic orbitals with an unpaired electron each, come close to each other and overlap to form a molecular orbital giving a covalent bond. It gives a quantum mechanical approach to the formation of covalent bonds with the help of wavefunctions using attractive and repulsive energies when two atoms are brought from infinity to their internuclear distance.
