32. An unknown compound with a molecular formula of C8H18 reacts with chlorine in the presence of light and heat. From the reaction mixture only one monochlorination product (i.e., only one compound dichloro-, with the formula C8H17C1) can be isolated. What is the most likely structure of the original unknown compound? trichloro-, and higher chlorinated products are also isolated, but consideration of these is unnecessary.)

6. a) The structural formulae of three isomers are shown below. - -CH2CH, CHO A OCH₂CCH3 B C-CH₂CH3 C With the aid of equations, describe the reactions of the isomers with i) Hydrazine, NH₂NH2 ii) lodine in an alkaline solution iii) Ammoniacal silver nitrate b) With the aid of equations, state the reagents and conditions required to prepare i) B from 1-phenylpropan-2-ol ii) C from benzene

The natural product halomon could theoretically arise from another naturally occurring compound known as myrcene. To accomplish this, a biochemical process that could deliver the synthetic equivalent of BrCi to all three double bonds would be required. (Chem Comm. 2014, 50, 13725) (a) Using three molar equivalents of BrCL please provide a mechanism to account for the formation of the bracketed structure (you do not need to show stereochemistry in this mechanism) HB (3 equiv) myrcene balomon 8.61a Add curved arrow(s) to show the mechanism steps.
