The maximum number of stereoisomers possible for the compound given below is ____ 
Answer
Answer (as printed): 4
The options are missing from the source scan for this question, so there is nothing here for this letter to point at. The letter is what the book printed.
Explanation
Answer: 4 — There is one stereocentre (the sec-butyl CH α to C=O) and a chiral biaryl axis, because the ortho substituents (acyl/NO₂ on one ring, Me/NO₂ on the other) block rotation. 2² = 4 stereoisomers.
