Concept explainers
(a)
Interpretation: The block diagram structures for all possible products of the partial hydrogenation of the given molecule with two
Concept introduction: Triacylglycerol is produced by the reaction of one molecule of glycerol and three molecules of fatty acid. The three hydroxyl groups of glycerol get esterified on reaction with fatty acids.
The process of addition of hydrogen atoms across the carbon-carbon double or triple bond is known as hydrogenation. Hydrogenation is the process of converting an unsaturated compound into a saturated compound.
