1. (3 points) Write the best Lewis structure for CH3N2+ , where the order of bonding is C-N-N. Show all bonds and all lone pairs. Describe the expected molecular (nuclear) geometry around the carbon and the central N.
C will be tetrahedral, the central N will be linear
2. (3 points) Write the best Lewis structure for HCONH2 . Show all bonds and all lone pairs. There is another contributing Lewis structure in which all atoms have an octet but there are formal charges. Write that structure as well.
3. (4 points) Complete each of the acid-base reactions shown below. For each completed reaction, identify the acid on each side and its pKa value. Determine whether the reaction would be favored to the right or to the left.
a) 
b)
