Electrophile\[NO_{2}^{\oplus }\]attacks the following In which cases,\[N{{O}_{2}}\]will be at meta position?

A) II and IV              

B) I, II and III

C) II and III          

D) Only I

Correct Answer: B

Solution :

Electrophile\[\overset{\oplus }{\mathop{N}}\,{{O}_{2}}\]attacks the following \[CC{{l}_{2}},\,\,N{{O}_{2}}\]and\[N{{H}_{3}}\]groups are electron withdrawing groups. All deactivating and\[m-\]directing. In negative charge on 0 is delocalised increasing electron density at o-and\[p-\]positions.
