Question

What is(are) the major product(s) of the following reaction? B HNO3 H2SO4 D. A and B E. A and C orbia ( che ama lenne

Answer 1

Part (A):- This is an electrophilic substitution reaction. As we know that, bromine will act as an ortho-para directing group. Generation of electrophile will take place in the first step. So, the major product will be also ortho-para products, which are given as below:-

. HNO3 or NO2 Ho +H-nson & H₂SOy where, o m Pa) for ortho For meta For para position position position. ноз , немоа Андоч — H₂SO4

NOL + oH2 (Attack (Electrophile) of electrophile) v0น NO2 (ontho product)

So, the complete reaction is given by: - By Dy By +H2O+H2SO4 HNO3W BMW Hoso TJ + Hasou a NO₂ (Ortho product) Nor by product. (para product , Then the correct option will be E A and C.

Part (B):- This is also an electrophilic substitution reaction. As we know that, chlorine will also act as an ortho-para directing group. Generation of electrophile will take place in the first step. So, the major product will be also an ortho-para product, which is given as below:-

ce o HNO3 H2SOY +NO₂ I (Elects ophile) (Attack af electrophile) + He o NO2 0 to Noce - → +420 +H250y Nor ce (major product) So the correct option will be ce NOL ce
