H -1 H Н. 4. In [B2H7], each B atom is approximately tetrahedral. (17 points) (a) How many valence electrons are present in this anion? (b) Assume each B atom is sp hybridized, after localizing 3 B-H terminal bonds per B atom, what orbital of B is responsible for the bridge interaction? (c) Follow your answer of (b), construct a molecular orbital diagram and draw the corresponding MOs to show the formation of [B2H] from two BH3 fragments and the bridging H unit B.11H -H B- H Н.
