A) o-dinitrobenzene
B) m-dinitrobenzene
C) p-dinitrobenzene
D) none of the above
Correct Answer: B
Solution :
\[-N{{O}_{2}},-CN,CHO\] \[-COR,-COOH,-COOR,\] \[-S{{O}_{3}}H\] etc. are meta directing group. These reduce the reactivity of benzene ring through resonance effect by reducing electron density on ortho and para position. Therefore, attack take place on meta position. Upon nitration nitrobenzene yield m-dinitro- benzene.You need to login to perform this action.
