In the following structural formulas, locate each chiral carbon atom.

(a) CH_{3}-\overset{\underset{|}{Cl} }{\underset{\overset{|}{Cl} }{C}} -\overset{\underset{|}{H} }{\underset{\overset{|}{OH} }{C}} -CH_{3}             (b) HO-\underset{\overset{||}{O} }{C}- \overset{\underset{|}{H} }{\underset{\overset{|}{NH_{2}} }{C}}-\overset{\underset{|}{H} }{\underset{\overset{|}{H} }{C}}-OH

(c) Cl-\overset{\underset{|}{H} }{\underset{\overset{|}{OH} }{C}} -\overset{\underset{|}{CH_{3}} }{\underset{\overset{|}{OH} }{C}} -Cl

STRATEGY

Look for carbon atoms that have four different atoms or groups bonded to them. As soon as you see two (or more) identical atoms or groups, you can stop counting. The C atom is not chiral.
