A chiral carbon is one that:
- Has only hydrogen atoms attached
- Is bonded to four different atoms or groups
- Has a double bond
- Is in an aromatic ring
Show answer and solution
Correct answer: B. Is bonded to four different atoms or groups
Chiral (asymmetric) carbon = sp³ C bonded to 4 different substituents.
Molecule with one chiral C is itself chiral (non-superimposable on its mirror image).
**Example:** 2-chlorobutane (C2 is chiral).
