(a)
Interpretation: The skeletal structure of the anabolic steroid methenolone from the given description is to be drawn.
Concept introduction: Steroids are composed of tetracyclic lipids. They have structure containing three six membered ring and one five membered ring. Some of the steroids are biologically active.
(b)
Interpretation: The skeletal structure of the anabolic steroid methenolone from the given description about the configurations at the stereogenic centers is to be drawn.
Concept introduction: Steroids are composed of tetracyclic lipids. They have structure containing three six membered ring and one five membered ring. Some of the steroids are biologically active.

(c)
Interpretation: The structure of Primobolan, the product formed on the treatment of methenolone with
Concept introduction: In the presence of base, the hydroxyl group loses its proton to form alkoxide. The alkoxide attacks on the carbonyl carbon of acyl chloride or acylic anhydride to leading to the formation of acyl group and removal of chloride. This process is known as acylation.
