JEE Main 4 April 2026, Shift 2, Chemistry Q66

Question 66 of 75 in this shift, Chemistry question 16 of 25, Section A.

The descending order of acidity among the following compounds is: A. phenol B. 4-nitrophenol (O2N\mathrm{O_2N} para to OH on the benzene ring) C. 4-methoxyphenol (H3CO\mathrm{H_3CO} para to OH on the benzene ring) D. 4-nitrobenzoic acid (O2N\mathrm{O_2N} para to COOH on the benzene ring) E. benzoic acid Choose the correct answer from the options given below:

The figure, in words

Five benzene-ring compounds: A phenol; B p-nitrophenol; C p-methoxyphenol (H3CO-); D p-nitrobenzoic acid; E benzoic acid.
  1. (1)B > D > E > A > C
  2. (2)D > B > E > A > C
  3. (3)C > A > B > D > E
  4. (4)D > E > B > A > COfficial answer
