How to Identify Chiral Centers in a Molecule

You need to be able to quickly spot chiral centers in molecules All straight-chain alkyl group carbons (CH 3 or CH 2 units) will not be chiral centers because these groups have two or more identical groups (the hydrogens) attached to the carbons Neither will carbons on double or triple bonds be chiral centers because they can't have bonds to four different groups
