Concept explainers

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.

Question

1. What happens to the axial bonds when a chair conformation is converted to another chair conformation? The overall process of converting one chair conformation to another chair conformation is known as RING INVERSION or ring flipping and is a very rapid process. The cyclohexane ring inverts approximately 10 time a second at room temperature. 2. Show this interconversion by drawing the two chair conformations and putting a reversible arrow between them to indicate a dynamic equilibrium. 3.
