Question 4
Answer
(B)
Explanation
A wax is an ester of a fatty acid and a fatty alcohol.
Question 5
Answer
(C)
Explanation
Water is added after reaction with grignard is complete because grignard has higher reactivity with water
Question 6
Answer
(D)
Explanation
Triglycerides are classified as simple lipids because they are formed from just two types of compounds: glycerol and fatty acids. In contrast, complex lipids contain at least one additional component, for example, a phosphate group (phospholipids) or a carbohydrate moiety (glycolipids).
