In each of the following, are they in the R configuration or the S configuration?

**Exercise: Identifying Functional Groups in Organic Molecules**

For each of the following molecules, please name the main functional group present:

(a)  
\[ \text{CH}_3 - \overset{0}{\underset{|}{\text{C}}}- \text{CH}_2 \text{CH}_3 \]

(b)  
\[ \text{CH}_3 - \overset{0}{\underset{|}{\text{C}}}- \text{CH}_3 \]

(c)  
\[ \text{CH}_3 - \overset{\text{OH}}{\underset{|}{\text{C}}}- \text{CH}_2 \text{CH}_3 \]

1. **Structure (a):**
   - Contains a carbon chain with a central carbon atom double-bonded to an oxygen atom. This is characteristic of a **ketone** functional group.

2. **Structure (b):**
   - Consists of a simple carbon chain with a central carbon atom double-bonded to two hydrogen atoms. This is indicative of an **alkane** functional group with no additional functional groups.

3. **Structure (c):**
   - Features a carbon chain where a central carbon atom is bonded to an OH group. This is typical of an **alcohol** functional group.

**Instructions:**
Identify the functional group in each molecule and consider how these groups affect the properties and reactions of the molecules.

Expert Solution
Step 1

The R and S configuration can de be described around the asymmetric center or the chiral center.

Chiral centers are those that have 4 different groups or atoms attached.

A chiral center is always sp3 hybridized

If no chiral center is attached, no R and S configuration can be described along with that carbon.
