Question

Which of the following is the correct expression for maximum number of configurational isomers?

n = number of asymmetric carbon atoms m = number of double bonds capable of showing geometrical isomerism

Ans. (B) 2 n+m . Sol. Each asymmetric carbon is one independent stereogenic element, and each stereogenic double bond is one more independent element. The number of independent stereogenic elements is therefore (n + m), and the maximum number of configurational isomers = 2 n+m .
