Total number of optically active isomers) of 2 3-dibromopentane is/are

1.	Total number of optically active isomers) of 2 3-dibromopentane is/are
Answer» Explanation: The maximum number of STEREOISOMERS is 2n , where n is the number of chiral centres. Since n=2 , the maximum number of stereoisomers is 22=4 . STRUCTURES 1 and 2 are two DIFFERENT nonsuperimposable mirror IMAGES of each other. But Structures 3 and 4 are meso compounds.
