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

Draw a chair conformation of cyclohexane with one CH₃CH₂ group and one CH₃ group that fits following description.

a trans-1,4-disubstituted cyclohexane with an equatorial CH₃CH₂ group

Expert Solution

Step 1:

Chair conformation of cyclohexane contains two types of hydrogen.

Equatorial hydrogens: These hydrogens lie around the equator of the ring.
Axial hydrogens: These hydrogens lie along the axis of the ring.

Two substituents are present on the ring. One is a methyl group and the other is an ethyl group.

Step 2:

Equatorial and axial hydrogens on a cyclohexane ring is described as follows:

Looking at 1,3,5-triethylcyclohexane we cannot tell the stability of the molecule from looking at the flat 2D drawing. Explain why we need to look at the 3D configuration and what conformation (axial,equatorial) would each of the three ethyl groups be in for the most stable configuration.
