(a)

Interpretation Introduction

To determine: The products, when HgSO4/H2SO4 catalysed hydration and hydroboration-oxidation are applied to hex1yne.

Interpretation: The products, when HgSO4/H2SO4 catalysed hydration and hydroboration-oxidation are applied to hex1yne to be shown.

Concept introduction: Hydroboration-oxidation reactions convert an alkyne molecule into ketone or aldehyde in the presence of disiamylborane and hydrogen peroxide through the two step mechanism, whereas an alkene molecule in hydroboration-oxidation reaction is converted into alcohol by the addition of water.

An acid catalysed hydration reaction of alkynes in the presence of mercuric sulphate gives ketone.

(b)

Interpretation Introduction

To determine: The products, when HgSO4/H2SO4 catalysed hydration and hydroboration-oxidation are applied to hex2yne.

Interpretation: The products, when HgSO4/H2SO4 catalysed hydration and hydroboration-oxidation are applied to hex2yne to be shown.

Concept introduction: Hydroboration-oxidation reactions convert an alkyne molecule in to ketone or aldehyde in the presence of disiamylborane and hydrogen peroxide through the two step mechanism, whereas an alkene molecule in hydroboration-oxidation reaction is converted into alcohol by the addition of water.
