There will be 4 structures possible when a cycloalkane having molecular formula [tex]C_6H_{12}[/tex] which have a 4-membered ring and have 2 substituents attached to two different carbons.
The structures are provided in the image attached.
The structures are stereochemical isomers or stereoisomers which means they have same formula and sequence of bonded atoms but differ in the three-dimensional orientation of the atoms in the space.
The IUPAC names of the structures are
A) trans -1,2- dimethylcyclobutane
B) cis -1,2- dimethylcyclobuatne
C) trans -1,3- dimethylcyclobuatne
D) cis -1,3- dimethylcyclobuatne
