They involve abnormal bonding for both elements involved.
Alfred Stock was the first to establish the naming of these compounds, and William Lipscomb won his Nobel Prize for research into their structure. They involve abnormal bonding for both elements involved. With normal covalent bonds, they would be electron deficient; they get around this by having various types of three-center bonds, where one electron pair is used to bond three atoms together. This involves "bridge" hydrogens being bonded to two other atoms, as well as the direct sharing of electrons by the other atomic species, which in isolation has three valence electrons. For ten points, identify these compounds of hydrogen with boron.
