2-methyl-2-hexanol was prepared by reacting an alkene with either hydroboration-oxidation or oxymercuration-reduction. Draw the structure of the alkene that was used to prepare the alcohol in highest yield. • You do not have to consider stereochemistry. • Indicate the method of preparation by drawing either BH3 (for hydroboration-oxidation), or Hg (for oxymercuration-reduction), in a separate sketcher. • If there is more than one alkene that can be used for a given method, draw all of them. • If either hydroboration-oxidation or oxymercuration-reduction can be used, just give the structures for one method. • Separate structures with + signs from the drop-down menu. *9⁹-85 ?

1 The structural prefix s- or sec- (for secondary-) and t- to tert- (for tertiary-) maybe incorporated in a name to designate a specific secondary or tertiary alkyl group, respectively. If no isomeric alkyl group of the same classification are possible. These prefixes are underlined italics and separated from the rest of the name by hyphens. The alkyl group represented by formula H3C CH2 CH3 CH3 Xs named as The parent chain in the compound Contains C atoms hence the alkene name for this parent chain is properly numbered.
