(a)
Interpretation:
The structures of dibromobenzene derivatives are to be drawn by assuming the correctness of Kekule structure of benzene.
Concept introduction:
Kekule structure is the representation of a compound by its Lewis structure. In this structure, the covalent bonds are shown for the bonded electron pairs. Melting point of a compound depends upon its molecular symmetry.
(b)
Interpretation:
The structures of dibromobenzene derivatives are to be assigned by assuming the correctness of Ladenburg structure of benzene.
Concept introduction:
Ladenburg benzene structure is also known as Prismane structure. The carbon and hydrogen atoms of a benzene molecule are represented as three prismane structures arranged in the form of a triangular prism.
(c)
Interpretation:
The mononitration products which were formed in the least amount are to be identified.
Concept introduction:
Nitration is a process in which a nitro group is substituted on the
(d)
Interpretation:
The differences in the spectra of dibromobenzene derivaties are to be stated.
Concept introduction:
The NMR spectroscopy is used to determine the number of equivalent and non equivalent carbon atoms and to identify the type of carbon atoms present in the compound.

- Compound X has molecular formula C5H10. In the presence of a metal catalyst, compound X reacts with one equivalent of molecular hydrogen to yield 2-methylbutane. (1) Suggest three possible structures for compound X. (2) Hydroboration-oxidation of compound X yields a product with no chirality centers. Identify the structure of compound X.arrow_forwardOn being heated with a solution of sodium ethoxide in ethanol, compound A (C7H15Br) yielded a mixture of two alkenes B and C, each having the molecular formula C7H14. Catalytic hydrogenation of the major isomer B or the minor isomer C gave only 3-ethylpentane. Suggest structures for compounds A, B, and C consistent with these observations.arrow_forwardGiven that naphthalene is insoluble in water and sublimes easily upon heating, describe two methods by which you could separate naphthalene and NaCL.arrow_forward

- Compound A (C5H8) readily reacts with bromine (Br2) at room temperature to discharge the purple colour of bromine and form Compound B (C5H8Br2). When Compound A is treated with H2 in the presence of a transition metal catalyst, it is converted to compound C (C5H10). When treated with HCl, compound A is converted to compound D (C5H9Cl). B, Cand D are saturated compounds. Given this information, propose structural formulas for compounds A, B, C, and D.arrow_forwardCompound A is a branched-chain alcohol that undergoes oxidation to produce compound B. Compound B is a ketone that gives positive triiodomethane reaction. Compound B is then reacted with phenyl magnesium bromide, C6H5MgBr in the presence of aqueous acid to form compound C.
