Chirality centers in rings

WebThe carbons in CH 3 or CH 2 are NEVER chirality centers. The chirality center must be the carbon bonded with a branch (or branches). sp 2 double bond carbon is NEVER a chirality center. Carbon in a ring can also be chirality center as long as it meet the two requirements. Not all the above compounds have a chirality center. Solution: WebAnswer (1 of 3): The reason that atoms on rings can be chiral is because, from the atom's persprective the two different sides of the ring look like different groups. Take a look at (S)-2-aminohexanol: As it turns out, the …
