Document Summary

The essentials: group 13 elements: boron, aluminum, gallium, indium and thallium, boron is the only nonmetal in the group, aluminum is the most abundant group 13 element. Bn structure consists of planar sheets of atoms like graphite. Bn and graphite have similar physical properties, both used as lubricants but bn is a white, nonconducting solid. The detail the group 13 elements: aluminum is highly abundant; thallium and indium are the least abundant of, 2 bbr3 (g) + 3 h2 (g) 2 b (s) + 6 hbr (g) Lewis acid: hydroboration, the reaction of diborane with alkenes in ether solvent, produces organoboranes that are useful intermediates in synthetic organic chemistry. + h+ b2h6 + h2. Lialh4 and ligah4 are useful precursors of mh3l2 complexes; lialh4 is also used as a source of h- ions in the preparation of metalloid hydrides, such as.
