JEE Main Chemistry question
Compounds [2-hydroxy-5-methylbenzoic acid], [3-methoxy-4-methyltoluene type anisole], and [an aryl ester, 4-methylphenyl benzoate-type] are separately subjected to nitration using HNO/HSO mixture. The major product formed in each case, respectively, is directed by the strongest activating/directing group present. [IIT JEE 2010]
Answer: (A)
Solution
Among competing substituents on a ring, the strongest electron-donating (*ortho*/*para*-directing) group controls the position of electrophilic nitration. In , –OH is a far stronger activator/director than –COOH or –CH, so nitration occurs *ortho*/*para* to –OH. In , –OCH (a strong donor by resonance)
