Predict Products Benzene Rings Electrophillic Aromatic Substitution

Question 1

Halogenation

Answer 1

X2, FeX3

E+= Cl or Br

Replaces H

Question 2

Nitration

Answer 2

HNO3, H2SO4

E+= NO2
Replaces H

Question 3

Sulfonation

Answer 3

SO3, H2SO4

E+=SO3H group replaces H

Question 4

Friedel-Crafts Alkylation

Answer 4

RCl, AlCl3
E+=R+
Replacement of H by R
Cl is leaving group, doesn’t go on ring

Question 5

Friedel crafts acylation

Answer 5

RCOCl, AlCl3

Add everything connected to Cl except Cl

Question 6

Bromination

Answer 6

Br2, FeBr3

Bromine is added to ring (more sub side)

Question 7

Chlorination

Answer 7

Cl2, FeCl3
Chlorine replaces H
Goes on more sub side

Question 8

Sn, HCl

Answer 8

Turns a NO2 group into an NH2 group

Question 9

Zn(Hg), HCl

Answer 9

Takes away keto group, carbon structure stays the same

Question 10

Br2, hv

Answer 10

Adds Br into most sub substituent possible, where a radical could form

Question 11

KMnO4

Answer 11

Turns existing substituent to carboxylic acid

Ketone with OH group

Question 12

KOC(CH3)

Answer 12

Cause an elimination with the Br or group at benzyllic position. Alkane to Alkene
