Examine the following for chirality centers:

(a) 2-Bromopentane

(b) 3-Bromopentane

(c) 1-Bromo-2-methylbutane

(d) 2-Bromo-2-methylbutane

Sample Solution A carbon with four different groups attached to it is a chirality center. (a) In 2-bromopentane, C-2 satisfies this requirement. (b) None of the carbons in 3-bromopentane has four different substituents, and so none of its atoms is a chirality center.
