As the bead engineer of your starship in charge of the warp drive, you notice that the supply of dilithium is critically low. While searching for a replacement fuel, you discover some diboron, B 2 . a. What is the bond order in Li 2 and B 2 ? b. How many electrons must be removed from B 2 to make it isoelectronic with Li 2 so that it might be used in the warp drive? c. The reaction to make B 2 isoelectroruc with Li 2 is generalized (where n = number of electrons determined in part b) as follows: B 2 → B 2 n + + n e − Δ E = 6455 k J / m o l How much energy is needed to ionize 1.5 kg B 2 to lhe desired isoelectroruc species?

Some important notes:
• Draw the major product, or products, of the reaction in the drawing area below.
• If there aren't any products, because no reaction will take place, check the box below the drawing area instead.
• Be sure to use wedge and dash bonds when necessary, for example to distinguish between major products that are
enantiomers.
