JEE Main 6 April 2026, Shift 2, Chemistry Q67

Question 67 of 75 in this shift, Chemistry question 17 of 25, Section A.

Consider the following organic reaction sequence. Choose the final product (X) from the following (consider the major product in all intermediate reactions) [figure: propanoic acid, CH3CH2COOH\mathrm{CH_3CH_2COOH}] →(i) NH3/Δ; (ii) NaOH/Br2; (iii) HNO2/H2O, 0∘C; (iv) C6H5N2Cl, 0∘C\xrightarrow{\text{(i) NH}_3/\Delta;\ \text{(ii) NaOH/Br}_2;\ \text{(iii) HNO}_2/\mathrm{H_2O},\ 0^\circ\mathrm{C};\ \text{(iv) C}_6\mathrm{H}_5\mathrm{N}_2\mathrm{Cl},\ 0^\circ\mathrm{C}} (X) Major Product

The figure, in words
