For a general unsymmetrical organic molecule containing exactly '' distinct stereogenic units, what — Isomerism and Stereochemistry Chemistry Question
Question
For a general unsymmetrical organic molecule containing exactly '$n$' distinct stereogenic units, what is the universal mathematical formula used to calculate the absolute total number of possible stereoisomers?
Answer: B
💡 Solution & Explanation
If an organic molecule is structurally unsymmetrical (meaning its terminal substituent groups are entirely different and it lacks any overall molecular symmetry axes), the total number of stereoisomers is simply derived from the permutation of each independent stereocenter, yielding exactly $2^n$.
