The three general positions of a disubstituted benzene ring are ortho, meta and para. Figure 1: The Effect of an Electron Donating Groups on a Benzene Ring The first scenario for adding an electrophile to a monosubstituted benzene ring is when the substituent is an electron donating group. WebApr 25, 2016 · Focusing inside the first set of parentheses, evaluate the power first, then the multiplication, and then the subtraction: (10 – 1 14 x 8) 4/4+5 = (10 – 1 x 8) 4/4+5 = (10 – 8) 4/4+5 = 2 4/4+5. Next, handle the expression in the exponent, evaluating the division first and then the addition: 2 1+5 = 2 6. To finish, evaluate the power:
