1.The chemistry of boron is similar to that of carbon. While the ground state of BH is a singlet with a covalent bond—see problem 5(a) in Homework 6)—there is an excited state of BH that involves a recoupled pair bond. Build coupling diagrams for triplet BH and then for doublet BH2 and singlet, trigonal planar BH3. The bond angle of BH2 is 129.

A sample coupling diagram for BH is attached below

Problem 5a is just the coupling diagram of BH

(a) BH (6 e*): B(1s2 2s22pz) * H(1s!) → BH(10202 308²) aßaßaß S= 0 (singlet) Ax=H(2.20) - B(2.04) = 0.16 (polarized slightly
