Answer to Question #144372 in General Chemistry for sharon

Question

1. An oil X has a saponification Value of 100 and an Oil Y has a saponification Value of 70. Which oil will have a high molecular weight and long fatty acid chain?

Answer 1

The higher the saponification value, the lower the fatty acids average length, the lighter the mean molecular weight, and vice-versa. In the question, it is shown that oil X has a saponification value of 100, and an Oil Y has a saponification value of 70. Therefore, Oil Y has a high molecular weight and a long fatty acid chain.
