Final answer:
The total number of stereoisomers for dichlorocyclopentane, which has two chiral centers, is four according to the formula 2^n. The correct option is (C).
Step-by-step explanation:
The total number of stereoisomers for a compound can generally be determined using the formula 2^n, where n is the number of chiral centers. The question refers to dichlorocyclopentane, which is assumed to have two chiral centers because it is not explicitly mentioned. Using the formula, the number of stereoisomers for dichlorocyclopentane would be 2^2 or four stereoisomers. This includes all possible configurations of the chiral centers.
