Question

Convert the ball-and-stick model of androsterone to (a) a skeletal structure using wedges and dashed wedges around all stereogenic centers; and (b) a three-dimensional representation using chair cyclohexane rings.

androsterone

Short answer

Answer

(a)

(b)

Step-by-step solution

Androsterone

Androsterone is a natural organic compound with a chemical formula C₁₉H₃₀O₂. It contains four cyclic rings (three 6-membered and one 5-membered), one OH group, and one C-O double bond.

At the 17^th position, the carbonyl group is present.
