There are four possible skeletons for a 6-C compound with a 4-C ring and no double bonds.
A cyclic compound is defined as the compound in which there is at least some of its atoms are connected to form a ring. Rings may be vary in size from three to many tens or even hundreds of atoms.
The minimum number of member of ring is 3.
The cyclic compound also known as ring compound.
All the four structure are isomers.
Isomers are the compound which have same empirical formula but have different structure.
Isomers are defined as the compounds which contain exactly the same number of atoms, i.e., they have strictly the same empirical formula, but they different from each other in the way in which the atoms are arranged.
Thus, we concluded that there are four possible skeletons for a 6-C compound with a 4-C ring and no double bonds.
