Sergey Bylikin, Gary Horner and, Brian Murphy Solutions for Chapter: Chemical Bonding and Structure, Exercise 11: Questions

Compare and contrast the allotropes of carbon (diamond, graphite, graphene, and ${\mathrm{C}}_{60}$) in terms of structure.

Compare and contrast the allotropes of carbon (diamond, graphite, graphene, and ${\mathrm{C}}_{60}$) in terms of bonding.

Compare and contrast the allotropes of carbon (diamond, graphite, graphene, and ${\mathrm{C}}_{60}$) in terms of intermolecular forces.

Compare and contrast the allotropes of carbon (diamond, graphite, graphene, and ${\mathrm{C}}_{60}$) in terms of melting points.

Compare and contrast the allotropes of carbon (diamond, graphite, graphene, and ${\mathrm{C}}_{60}$) in terms of electrical conductivity.

In chemistry, both terminology and models can often lead to certain assumptions. Suggest why the term "macromolecular" is incorrect based on IUPAC recommendations for covalent network solids such as graphite.

In chemistry both terminology and models can often lead to certain assumptions. The $\mathrm{O}-\mathrm{Cl}-\mathrm{O}$ bond angle in ${\mathrm{OCl}}_2$ is $110.9°$. Discuss whether this bond angle agrees with predictions of bond angles based on the model of VSEPR theory.

Suggest why VSEPR theory does not work for the majority of transition metal complexes, such as ${\left[{\mathrm{FeCl}}_4\right]}^{2-}$, but does for a few complexes, such as ${\left[{\mathrm{MnO}}_4\right]}^{-}$.
