1. (4 pts) Complete each of the following reactions by adding the missing part:

a)

b)

c)

d)

2. (2 pts) Gold is in period 11. Metallic gold can be dissolved in the presence of cyanide ( -CN ), a strong 2-electron ligand for gold in its +1 state. Show how the complex Au(CN)4 -3 follows the 18-electron rule by identifying the 18 electrons.

Au = 11 e- , therefore Au+ = 10 e- , each CN- = 2 e- , total 18 e-

3. (4 pts) Show a sequence of reactions that could be used to prepare the target compound shown below. You may start with any alcohol or carbonyl compound having 3 carbons or fewer.
