6. Steroid

Step-by-step solution

Step-1. Explanation of part (a), (b) and (c):

Glyceryl tristearate is a triglyceride which is derived from three units of stearic acid. Most triglycerides are derived from at least two and commonly three different fatty acids. It finds application as hardening agent in the manufacture of candles and soap.

Tetradecyl heptadecanoate is a wax. Waxes refer to the mixture of long chain non-polar lipids forming a protective coating on plant leaves. All waxes are water-resistant materials made up of hydrocarbons or ketones or diketones etc.

Step-2. Explanation of part (d), (e) and (f):

Peruvin is a sesquiterpene. Sesquiterpenes are a class of terpenes that consist of three isoprene units and often have the molecular formula. Sesquiterpenes may be cyclic or contain rings.
