- 5. (a) Compound A with molecular formula C7H8 is produced when benzene reacts with chloromethane in AICI3. When A is treated with acidic KMNO4 solution, compound B is formed. When A is treated with conc. HN0; in conc. H2SO4, a yellowish oil solution, C is formed. Draw the molecular structure of A, B and C and write an equation for the formation of A from benzene.arrow_forward(c) Alkenes can be transformed into epoxides by an epoxidation reaction. If the following hexenes are all subjected to an epoxidation reaction, which one would give an achiral epoxide? Explain your answer. 1-hexene cis-2-hexene trans-2-hexene cis-3-hexene trans-3-hexenearrow_forward(a) Cyclohexa-1,3-diene can be converted into a tetrasubstituted haloalkane when reacted with bromine in ether. Write a balanced chemical equation for the reaction that occurs and state the expected observation. (b) Compound A and B are alkenes with the same molecular formula C5H10. Compound A is a branched-chain alkene while compound B is a straight-chain alkene. The reaction between compound A with hydrogen bromide produces major product C which is optically active. (i) Draw TWO (2) possible structures for compound B. (ii) Outline the mechanism for the reaction between compound A with hydrogen bromide to form major product C. (iii) Name the product formed when compound A undergoes bromination reaction.arrow_forward
