For highly symmetrical organic molecules containing an ODD number ('') of chiral centers, what is th — Isomerism and Stereochemistry Chemistry Question

💡 Solution & Explanation

Symmetrical molecules with odd chiral centers feature a central pseudo-chiral carbon that can generate meso forms. The formula for active isomers is $2^{n-1} - 2^{(n-1)/2}$, and for meso is $2^{(n-1)/2}$. When summed to find the total stereoisomers, the subtractive and additive meso terms cancel perfectly, leaving the simplified Total formula as exactly $2^{n-1}$.
