Question

Which of the lipids in Figure LP2 is likely to have the highest boiling point? Structure III has the lowest melting point. Structures I. II and III have similar melting points. Structure III has the largest molar mass and the highest melting point. Structure I has the highest melting point. Structure II is a trans-fat with the highest melting point. Which of the statements about the lipids in Figure LP 2 is correct? Catalytic hydrogenation of structure III will change this lipid from a fat to an oil. Structures I and II cannot undergo based-catalyzed saponification. Saponification of structure III produces fatty acid chains known as soap micelles. Catalytic hydrogenation of structure III will lead to a hardening of this oil. Structures I-III are all simple lipids.

Explanation / Answer

The number of carbons in Structure-3 are greater than the other two.So, the molar mass is high.

So, correct option is (c)

(2)

Catalytic hydrogenation of structure -3 will lead to hardening of the oil. Since it has 2 double bonds.

So, the correct option is (D)
