1sorry in case of 1,3 anhydride formation is also not possible
17 Answers
1i will take third one as inorganic product in that case solution given by anurag is quite right
33I can't understand..
"A on treatment with Br2/Fe yields 3 products in principle but in actual practice,only 2 of these are produced as mono-bromo derivative"
is it means 2 mono bromo products and one dibromo.. but then no structure i am getting for A
1?A
benzene upar ethane hai n niche (para) ethane hai

24Gaurav Sir , the exact language is """ A on treatment with Br2/Fe yields 3 products in principle but in actual practice,only 2 of these are produced as mono-bromo derivative"""
1anurag this is most probable ans but this one not satisfying the second rxn as i have mentioned earlier infact no comp is satisfying the second rxn
1eureka can u check the Br2/Fe part of the question i am not getting the point is "two are mono bromo derivative " is third a non mono bromo derivative or Br is just not directly attached with the ring
39ya u are right, but generally we come across cases where mostly 1,2 are present.
62but in exam I think only say that 1,2 is not formed if anhydride is not formed.
I think I am pretty sure on this one..
39only 1,4 dude. 1,2 readily form a cyclic anhydride. 1,3 its rare but chances are possoble.
but 1,4 being very far away, no chance at all.
21i have a small question, what are cases when anhydride is not formed?
62No anhydride and 3 products being formed says that it has to be a 1,4 species... on the benzene ring
so C should be...
