Both anthracene and phenanthrene will undergo addition with Br2. Anthracene adds Br2 at the 9- and 10-position. Is this consistent with the MO(s) shown in the SHMO program? Explain. Use the SHMO program to predict where Br2 will add to phenanthrene by drawing the product of Br2 addition to phenanthrene
