3-Methylpentane does not have a chirality center. A chirality center (or chiral center) is typically a carbon atom that is bonded to four different groups. In the case of 3-methylpentane, the structure is:
CH3
|
CH3-CH2-CH-CH2-CH3
The carbon atoms in 3-methylpentane are not bonded to four different substituents. Specifically, the carbon at the 3rd position (the one with the methyl group attached) is bonded to two hydrogen atoms and two other carbon atoms (making it not chiral). Therefore, 3-methylpentane is achiral and does not have a chirality center.
