Draw three resonance structures for CS,. This species has its three atoms bonded sequentially in the following fashion: S-C-S. Draw your resonance structures so that the atoms in them are bonded together in this order. Select the most important resonance structure for this species based on the formal charges on the atoms of the three resonance structures you have drawn. Select the choices from below which make the statements true about this (most important) resonance structure. (a) The leftmost bond (between S and C) is a single v bond. (b) The rightmost bond (between C and S) is a single v bond. (c) The formal charge on the leftmost (S) atom is -Select-v (d) The formal charge on the central (C) atom is -Select-v (e) The formal charge on the rightmost (S) atom is Select-v (f) The number of nonbonding pairs (lone pairs) of electrons in the leftmost (S) atom is -Select-v pairs. pairs. (g) The number of nonbonding (lone) pairs of electrons in the rightmost (S) atom is –Select-
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.
