The diagrams should be flipped (the constitutional isomer one belongs where the geometric isomer one is, and vice versa).

In reply to Tanmay. That's a great exercise for you to work on! Start by drawing cyclobutane, and then making all the chlorines "wedges" (or dashes, you'll get the same thing). Then, systematically "flip" the dashes into wedges and compare to see if they are different isomers.

How many geometrical isomers of 1,2,3,4 tetrachlrocyclobutane is possible?

In reply to Muttalib Sheriff. A cyclohexane ring is *configurationally* locked. Meaning that groups can't flip on to the other *face* of the ring. i.e. we can't do a ring flip to convert (for example) cis-1,2-dimethylcyclohexane to trans-1,2-dimethylcyclohexane. A "ring flip" just interconverts which groups are axial and which are equatorial.

In the YouTube video you mentioned at the beginning, you say that cyclohexane is conformationally locked. Then how does it undergo ring flip.

[…] Rings of size <8 cannot turn inside-out, meaning that configurations of substituents relative to each other are locked. The simple way to say this is that it leads to the existence of cis and trans isomers for the disubstituted cases ( sometimes called “geometric isomers”) – e.g. cis- and trans- 1,2-dimethylcyclohexane.
