Chapter 10: Q23CQ (page 467)

In a buckyball, three of the bonds around each hexagon are so called double-bonds. They result from adjacent atoms sharing a state that does not participate in the sp2 bonding. Which state is it, and what is this extra bond σ-bond or a π-bond? Explain.

Short Answer

Expert verified

The state that does not participate in sp2 bonding is the remaining 2p state.

Step by step solution

01

Significance of double bond

In this context, double bonds are referred to as "conjugated," and because they represent an improved conformational stability, they are energetically preferred as reactants in many scenarios and combinations.

02

Step 2:

This is the state that participates in the double bonding. Since, the remaining 2p state will be perpendicular to the other bonds.

03

Step 3:

The extra bond must have the co-valent electron density largest off-axis.

Hence, it thus form π-bond.

Question: - Verify using equation (10-12) that the effective mass of a free particle is m.

Brass is a metal consisting principally of copper alloyed with a smaller amount of zinc, whose atoms do not alternate in a regular pattern in the crystal lattice but are somewhat randomly scattered about. The resistivity of brass is higher than that of either copper or zinc at room temperature, and it drops much slower as the temperature is lowered. What do these behaviors tell us about electrical conductivity in general?

The energy necessary to break the ionic bond between a sodium ion and a fluorine ion is 4.99eV. The energy necessary to separate the sodium and fluorine ions that form the ionic NaFcrystal is 9.30eV per ion pair. Explain the difference qualitatively.

In diamond, carbon’s four full (bonding) s and p spatial states become a band and the four empty(anti bonding) ones becomes a higher energy band. Considering the trend in the band gaps of diamond, silicon, and germanium, explain why it might not be surprising that “covalent” tin behaves as a conducting metallic solid.

Exercise 29 notes that more energy is required to ionize sodium that is retrieved by adding that electrons to an isolated chlorine atom, but the NaCl bond represents a lower energy because the attracting ions draw close together. Quantifying the energy-lowering effect of having alternating plus and minus charges can be rather involved for 3D lattice, but a one dimensional calculation is instructive. Consider an infinite line of point charges alternating between +e and –e, with a uniform spacing between adjacent opposite charge of a. (a) The electrostatic potential energy per ion is the same for a given positive ion as for a given negative ion. Why? (b) Calculate the electrostatic potential energy per ion for simplicity. Assume that a positive charge is at the origin. The following power series expansion will be helpful: ln(1+x)=-∑n=1γ(-x)nn.
