You need to be able to assign whether a chiral … WebA chiral center is an atom (usually a C atom but may be N,S,P,Si, etc) bonded tetrahedrally to four dofferent atopms or groups of atoms, called ligands. In compound (3), the carbon atom carrying the -OH group is a chiral center as the double bond in the ring is placed unsymmetrically.
