Match each pathway from List-I with an appropriate structure from List-II and select the correct answer using the code given below the lists. #tag# [IIT 2014] #sol# (A) [/esquestion] [esquestion] The major product of the reaction is : #tag# [IIT 2015] #sol# (A) [/esquestion] [esquestion] Aniline reacts with mixed acid (conc. HNO, and conc. $\mathrm{H}_{2} \mathrm{SO}_{4}$ ) at 288 K to give P (51%), Q (47%) and R (2%). The major product(s) the following reaction sequence is (are) :- #tag# [JEE Adv. 2018] #sol# (C) [/esquestion] [esquestion] In the following reaction sequence, the correct structure(s) of X is (are) #tag# [JEE Adv. 2018] #sol# (D) [/esquestion] Treatment of benzene with CO/HCl in the presence of anhydrous $\mathrm{AlCl}_{3} / \mathrm{CuCl}$ followed by reaction with Ac2O/NaOAc gives compound X as the major product. Compound X upon reaction with $\mathrm{Br}_{2} / \mathrm{Na}_{2} \mathrm{CO}_{3}$, followed by heating at 473 K with moist KOH furnishes Y as the major product. Reaction of X with $\mathrm{H}_{2} / \mathrm{Pd}-\mathrm{C}$, followed by $\mathrm{H}_{3} \mathrm{PO}_{4}$ treatment gives Z as the major product. (There are two questions based on PARAGRAPH "X", the question given below is one of them) [esquestion] The compound Y is :- #tag# [JEE Adv. 2018] #sol# (B) [/esquestion] [esquestion] The compound Z is :- #tag# [JEE Adv. 2018] #sol# (C) [/esquestion] An organic acid P $\left(\mathrm{C}_{1} \mathrm{H}_{12} \mathrm{O}_{2}\right)$ can easily be oxidized to a dibasic acid which reacts with ethyleneglycol to produce a polymer dacron. Upon ozonolysis, P gives an aliphatic ketone as one of the products. P undergoes the following reaction sequences to furnish R via Q. The compound P also undergoes another set of reactions to produce S. (There are two questions based on PARAGRAPH "A", the question given below is one of them) [esquestion] #tag# [JEE Adv. 2018] #sol# (A) [/esquestion] [esquestion] The compound R is (A) (B) (C) (D) #tag#[JEE Adv. 2018] #sol# (A) [/esquestion] [esquestion] The compound S is #tag# [JEE Adv. 2018] #sol# (B) [/esquestion]
