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: The diagram shows the energy bands of a tunnel diode as the potential difference is increased. In this device high impurity atom density causes the occupied donor and unoccupied acceptor levels to spread into impurity bands which overlap respectively the n-type conduction- and the p-type valence bands. In all unbiased diodes, the depletion zone between the n-type and p-type bands constitutes a potential barrier (see Section 6.2) but in the tunnel diode it is so thin that significant tunnelling occurs. The current versus voltage plot shows that unlike a normal diode significant current begins to flow as soon as there is an applied voltage—before the bias voltage is Egap /e. It then decreases (so called negative resistance) before again increasing in the normal way. Explain this behavior.

The diagram shows an idealization of the "floating magnet trick" of Figure 10.50. Before it is cooled, the superconducting disk on the bottom supports the small permanent magnet simply by contact. After cooling, the magnet floats. Make a sketch, showing what newmagnetic fields arse. Where are the currents that produce them?

The "floating magnet trick" is shown in Figure 10.50. If the disk on the bottom were a permanent magnet, rather than a superconductor, the trick wouldn't work. The superconductor does produce an external field very similar to that of a permanent magnet. What other characteristic is necessary to explain the effect? (Him: What happens when you hold two ordinary magnets so that they repel, and then you release one of them?)
