reaction , if any, of D2SO4 in D2O with (a)
C6H5SO3H (b) C6H5OH
(c) C6H6

Expert Answer
a) There is no ring deuteration because - SO3H is deactivating. However, the acidic H is exchanged for D to give C6H5SO3D. At elevated temperatures desulfonation can occur giving initially C6H5D.
b) o,p-Orientation yields 2,4,6-triD- C6H2OD.The acidic H is exchanged.
c) Slow reaction produces hexadeutrobenzene because there is no activating or orienting substituent.
