Get started for freeThe oxalate ion, \(\mathrm{C}_{2} \mathrm{O}_{4}^{2-}\), has the skeleton structure (a) Complete the Lewis structure of this ion. (b) Draw three resonance forms for \(\mathrm{C}_{2} \mathrm{O}_{4}{ }^{2-}\), equivalent to the Lewis structure drawn in (a). (c) Is a resonance form of the oxalate ion?
In each of the following molecules, a central atom is surrounded by a total of three atoms or unshared electron pairs: \(\mathrm{SnCl}_{2}, \mathrm{BCl}_{3}, \mathrm{SO}_{2}\). In which of these molecules would you expect the bond angle to be less than \(120^{\circ}\) ? Explain your reasoning.
Based on the concept of formal charge, what is the central atom in (a) HCN (do not include \(H\) as a possibility)? (b) \(\mathrm{NOCl}(\mathrm{Cl}\) is always a terminal atom)?
Dinitrogen pentoxide, \(\mathrm{N}_{2} \mathrm{O}_{5}\), when bubbled into water can form nitric acid. Its skeleton structure has no \(\mathrm{N}-\mathrm{N}\) or \(\mathrm{O}-\mathrm{O}\) bonds. Write its Lewis structure.
In each of the following polyatomic ions, the central atom has an expanded octet. Determine the number of electron pairs around the central atom and the hybridization in (a) \(\mathrm{SF}_{2}{ }^{2-}\) (b) \(\mathrm{AsCl}_{6}^{-}\) (c) \(\mathrm{SCl}_{4}{ }^{2-}\)
