Four

Explanation:

2,2-dimethylpentane looks like this:

The #Cl# may be at one of the three methyl groups at the end (the C1 also forms a methyl group). If it is on one of the 2,2-methyls, we change that to C1:

1-chloro 2,2-dimethylpentane

Or it may be at C3, C4 or C5

3-chloro 2,2-dimethylpentane

4-chloro 2,2-dimethylpentane

5-chloro 2,2-dimethylpentane

The C2 cannot take the #Cl# as it already has its four bonds occupied bij other carbon atoms (there is no H to replace).
