Question
An aspiring chemist analyzes a molecule and identifies a carbon atom bonded to four entirely different groups. However, the carbon is involved in a double bond. Can this specific carbon act as a genuine chiral stereocenter?
Answer: C
π‘ Solution & Explanation
A true chiral stereocenter (asymmetric carbon) is strictly defined as an $sp^3$ hybridized, tetrahedral atom that is covalently bonded to exactly four completely different atoms or groups. An $sp^2$ hybridized carbon (involved in a double bond) can only accommodate a maximum of three attached groups, making it physically impossible for it to act as an asymmetric chiral center.
