Question
Toluene, when treated with Br2 / Fe, gives p-dromotoluene as the major product because the CH2 group :
Options
A.is para-directing
B.is meta-directing
C.activates the ring by hyperconjugation
D.deactivates the ring
Solution
-CH3 gp. when attached to bezene ring acts as electron releasing grop due to hyperconjugation.
The incrasing electron density appears at o/ p positions i.e., why CH3 gp. o/p directing for incoming E+
