Final answer:
Scheme B and Scheme D will yield 3-methyl-3-hexanol.
Step-by-step explanation:
The reaction scheme(s) that will yield 3-methyl-3-hexanol is Scheme B and Scheme D.
This is because Scheme B includes 3-methylhexane, which can be oxidized to form 3-methyl-3-hexanol. Scheme D includes 4-methyl-1-hexene, which can undergo hydroboration-oxidation to yield 3-methyl-3-hexanol as well. The other options do not contain the necessary starting compounds to produce 3-methyl-3-hexanol.
