Options:
Answer:
B
Solution:
Ans. (B) 2.
Sol. Every ortho position of the biphenyl carries a bulky group (NO2 or CF3), so rotation about the biaryl bond is blocked, and each ring bears two different ortho substituents. The molecule is axially chiral (atropisomeric) and exists as an enantiomeric pair : 2 stereoisomers.
