A) \[COCH{{3}_{}}\]
B) \[~N{{H}_{2}}\]
C) \[~NHCOC{{H}_{3}}\]
D) ?COOH
Correct Answer: B
Solution :
2 and 6 are ortho position 4 is para position 3 and 5 are meta position with respect to the substituent - X. Aromatic compounds undergo electrophilic substitution reaction. Those groups which increase the electron density on ortho, para position (\[viz,-C{{H}_{3}},-{{C}_{2}}H{{ & }_{5}},-OH,-Br,-N{{H}_{2}},-NHR\]etc.) are called ortho/para directing group substituents, which increases electron density on meta position (\[-N{{O}_{2}},-CN,-CHO,-COR.\]\[-COOH,-COOR,-S{{O}_{3}}H\]etc. are meta directing groups.You need to login to perform this action.
