In the reaction for dinitration of m-cresol with conc. HNO_3, the major dinitrated product X is **[DCE 2009]**

JEE Main Chemistry question

In the reaction for dinitration of -cresol with conc. , the major dinitrated product is **[DCE 2009]**

(A)4,6-dinitro-3-methylphenol (dinitro ortho/para to OH and compatible with methyl's directing effect)Correct
(B)A dinitro isomer with both NO2 adjacent to CH3 only
(C)A dinitro isomer with one NO2 meta to OH
(D)An isomer violating directing-group compatibility

Answer: (A)

Solution

Both the and groups on -cresol are ortho/para directors; nitration occurs preferentially at ring positions that are simultaneously favoured by both groups (reinforcing directing effects), giving the dinitro product in which the
