What happens when the given compound is heated?
Options:
Answer:
A
Solution:
Ans. (A) Racemic mixture.
Sol. Biphenyl-2,2'-disulphonic acid is axially chiral (atropisomeric) because the bulky ortho SO3H groups restrict rotation about the biaryl bond. On heating, enough energy is available for the two rings to rotate past each other, so an optically active sample racemises to give a racemic mixture.
