The image shows two organic chemistry structures known as cyclohexane chair conformations. 1. **Left Structure:** The cyclohexane is in a chair conformation, where one carbon is above the plane and another carbon is below, forming a "chair" shape. The axial and equatorial positions are not explicitly marked. 2. **Right Structure:** Another cyclohexane chair conformation is shown. It appears there is a subtle shift, possibly indicating a ring flip, where the positions of axial and equatorial hydrogens are inverted. These drawings help illustrate the concept of conformational isomerism in cyclohexane, where the three-dimensional arrangement of atoms can change, affecting molecule stability.

Alkanes and Cycloalkanes

Alkanes are saturated organic compounds which are made up of C and H atoms. Alkanes have the general formula of CnH2n+2. Alkane contains sp3 hybridized carbon atoms with four sigmas (σ) bonds & every hydrogen atom is connected with one of the carbon atoms. The size of the alkane could be determined by the number of carbon atoms located in it.
