If a triglyceride contains linoleic, linolenic and oleic acids how many moles of hydrogen are required to fully hydrogenate one mole of this triglyceride?
A) 3
B) 4
C) 5
D) 6

Question

Quizplus · Accepted Answer

One mole of triglyceride contains three moles of fatty acids. Linoleic acid has 18 carbons and 2 double bonds, linolenic acid has 18 carbons and 3 double bonds, and oleic acid has 18 carbons and 1 double bond. Therefore, one mole of this triglyceride has a total of 6 double bonds. Each double bond requires one mole of hydrogen to be hydrogenated. Therefore, one mole of this triglyceride requires 6 moles of hydrogen to be fully hydrogenated.
