Functional Group Identification Worksheet with five organic molecules for identifying functional groups.

Let's solve the Functional Group Identification Worksheet step by step.

Part 1: Identify the functional groups on the following organic molecules

We will analyze each molecule based on its structure and identify the key functional group present.

---

#### a.
```
H O
| ||
H - C - C - H
| |
H OH
```

- The central carbon has a double bond to oxygen (C=O) and is also bonded to an -OH group.
- This is a carboxylic acid functional group: -COOH.
- The molecule is ethanoic acid (acetic acid).

✔ Functional Group: Carboxylic Acid

---

#### b.
```
H O O H
| || | |
H - C - C - O - C - C - H
| | | |
H H H H
```

- There is a carbonyl group (C=O) attached to an oxygen that is connected to another carbon chain.
- This is an ester functional group: -COOR, where R is an alkyl group.
- The structure shows ethyl ethanoate (ethyl acetate).

✔ Functional Group: Ester

---

#### c.
```
H O N H
| || | |
H - C - C - N - C - H
| | | |
H H H H
```

- There is a carbonyl group (C=O) bonded directly to a nitrogen atom (N).
- This is an amide functional group: -CONH₂ or similar.
- The molecule is acetamide.

✔ Functional Group: Amide

---

#### d.
```
H OH H
| | |
H - C - C - C - H
| | | |
H H H H
```

- One of the carbon atoms has an -OH group attached.
- This is an alcohol functional group: -OH.
- The molecule is propan-2-ol (isopropyl alcohol).

✔ Functional Group: Alcohol

---

#### e.
```
H H Br H
| | | |
H - C - C - C - C - H
| | | | |
H H H H H
```

- One of the carbon atoms is bonded to a bromine (Br) atom.
- This is a haloalkane (specifically, bromoalkane) functional group: -Br.
- The molecule is 1-bromobutane.

✔ Functional Group: Alkyl Halide (Bromoalkane)

---

✔ Summary for Part 1:

| Molecule | Functional Group |
|---------|--------------------------|
| a | Carboxylic Acid |
| b | Ester |
| c | Amide |
| d | Alcohol |
| e | Alkyl Halide (Bromoalkane) |

---

Part 2: Draw the following organic compounds, and state the organic family they belong to

> *(Note: The second part says "Draw the following organic compounds..." but no list is provided in the image you uploaded. It seems like this section might be missing the actual compound names or formulas.)*

However, if this was intended to be a continuation, please provide the names of the compounds you'd like drawn (e.g., ethanol, propanal, etc.), and I can help draw them and classify them.

But since nothing is listed, we'll assume it's incomplete.

---

✔ Final Answers:

#### 1. Identify the functional groups:

a. Carboxylic Acid
b. Ester
c. Amide
d. Alcohol
e. Alkyl Halide (Bromoalkane)

If you have the second part with specific compound names (like "butanone" or "methylamine"), feel free to share them, and I’ll draw the structures and classify them!
