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.

## Practice Problems: Newman Projections

### 5A. For chains, draw Newman projections of all conformations around a given bond and determine their energy

**OCSL 6.1 – 6.14**

**5A.1** Draw a Newman projection for the following around the indicated bond:

The following sub-questions each involve drawing specified Newman projections:

- **(a)**
- Structure: A given chain with a specific bond indicated for projection.
- Key Detail: Analyze the chain and focus on the indicated bond for Newman projection.

- **(b)**
- Structure: Another specific chain with a different bond indicated with an arrow for Newman projection.
- Key Detail: Arrows indicate which bond to consider for the projection.

- **(c)**
- Structure: A chain with an indicated bond using an arrow for Newman projection.
- Key Detail: The chain might have varying substituents or branches to consider in the projection.

- **(d)**
- Structure: A chain with an arrow indicating a specific bond for the Newman projection.
- Key Detail: The chain’s conformation may vary and should be analyzed around the indicated bond.

- **(e)**
- Structure: A more complex chain with an arrow showing the bond for projection.
- Key Detail: Evaluate the chain’s structure, especially around branched compounds, for a precise Newman projection.

- **(f)**
- Structure: A chain with an indicated bond for the Newman projection.
- Key Detail: Focus on the conformation around the specified bond to accurately draw the projection.

For each part, students should identify the specific bond highlighted by the arrow and draw the Newman projection looking down that bond. This exercise helps in understanding the spatial arrangements and different conformations molecules can adopt. Evaluating the energy of these conformations is crucial for understanding molecular stability.
