What functional group is expected when hex-3-yne is treated with disiamylborane, followed by treatment with basic hydrogen peroxide? a ketone b aldehyde c diol d ether

Ketone.

Explanation:

Disiamylborane is used for hydroboration of an alkene or alkyne.

An alkene hydroboration gives an alcohol and an alkyne gives carbonyl compound.

A terminal alkyne gives aldehyde while a non terminal alkyne gives ketone or hydroboration.

The role of hydrogen peroxide is that it results in oxidative hydroboration and hydroboration can also be reductive if we use Zinc.

a chemical reaction

explanation:

your answer would be “dry”
