Question

Nandrolone nabolic steroid that has been used illegally by athletes. How many stereogenic centers does it have? OH nandrolone

how many stereogenic centers does it have? 0, 2, 4, or 6?

Answer 1

Ans :- There are 6 stereogenic centers in the given structure.

Stereogenic centers :- Contain not only chiral centers (Carbon in which all the four groups are different) but also geometrical centers.

In the given structures,

Geometrical centers = 0 and

Chiral centers = 6

So,

Stereogenic centers = geometrical centers + chiral centers = 0 + 6 = 6

* = Stereogenic center Not Stereogenic center:
