Chemistry - GOC Question with Solution | TestHub

The three C=C bonds of the central ring are saturated. Each four-membered ring can only be cis-fused to the central ring, so the six new C-H bonds are set by which face each ring fusion takes. The three fusions can all lie on the same face (one achiral product) or two on one face and one on the other (a second achiral product). x = 2.
