Chemistry - STEREO ISOMERISM Question with Solution | TestHub

The molecule has three stereogenic elements : the two CH=CHCl double bonds (E/Z each) and the cis/trans arrangement of the two side chains on the cyclopentane ring.

Because the two -CH=CHCl arms are identical, the (E,Z) and (Z,E) combinations are the same molecule, so the double bonds give 3 distinct cases : (E,E), (Z,Z) and (E,Z). For each, the ring junction can be cis or trans.

Total = 3 x 2 = 6.

Ans. 6
