- 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. (g) The number of nonbonding (lone) pairs of electrons in the rightmost (S) atom is -Select-- v pairs.Explain the Below fact ?
