Interpretation Introduction
Interpretation:
Reactants required to form products in the reactions by Stille coupling reaction are to be determined.
Concept introduction:
Stille coupling is a reaction in which organotin compounds are coupled with organic halides. Here, organotin compounds are used as coupling agents.
This reaction takes place in the presence of palladium catalyst. This reaction is commonly used for

When the nitrogen-containing aromatic heterocyclic compounds 1 and 2 are treated with HCl, only 1 forms the hydrochloride salt, whereas compound 2 is unreactive. Provide an explanation for this observed reactivity.
A certain compound is known to contain an aromatic benzene ring but failed to produce a fragrant yellow solution upon subjecting it to the nitration test. What may be a possible explanation for this?
A. The benzene ring is part of a highly conjugated, blue dye molecule.
B. The benzene ring contains a strong electron-withdrawing group.
C. The benzene ring has no available sites left for electrophilic attack.
D. All of the given.
Kindly explain your answer in detail.
Compound A has the molecular formula C14H25Br and was obtained by thereaction of sodium acetylide with 1,12-dibromododecane. On treatment ofcompound A with sodium amide, compound B (C14H24) was obtained. Ozonolysisof compound B gave the diacid HO2C(CH2)12CO2H. Catalytic hydrogenation ofcompound B over Lindlar palladium gave compound C (C14H26), andhydrogenation over platinum gave compound D (C14H28). Further, C yieldedO=CH(CH2)12CH=O on ozonolysis. Assign structures to compounds A through Dso as to be consistent with the observed transformations.
