Question

Draw the structures of two stereoisomeric alkenes that would give 3-hexanol as the only major product of hydroboration followed by treatment with alkaline H2O2:

Answer 1

Answer:

cis-3-hexene and trans-3-hexene

Explanation:

Hydroboration oxidation is a method of preparation of alcohol from alkene.

Hydroboration follows anti-Markovnikoff rule in which alcohol group attached to less substituted carbon. Stereochemistry of the product is always syn that is H and OH attached to the same side of the double bond.

cis-3-hexene and trans-3-hexene undergoes hydroboration to form 3-hexanol.
