Q. The total number of isomers including stereoisomers for 1,2-dimethyl cyclobutane is:

2, one cisand one trans(both optically inactive)

3, one cisand two optically activetrans forms

3, one transand two optically active cis forms

4, two cis (optically active) and two trans(optically active)

Correct answer is (b) 3, one cisand two optically activetrans forms
