Question

1. List the following four compunds in increasing order of polarity:

-Resorcinol, Anthracene, Benzoic Acid, and 4-Amino-1-naphthanesulfonic Acid, sodium salt.

2. Predict which solvent (ligroin, water, toluene) might solubilize each solute from the compounds listed above. Why in each case?

Answer 1

I would like to help but not by answering the question. Exactly what do you not understand about the questions.

Answer 2

I'll try to answer those questions. But I need someone to check for me.

1) anthracene<resorcinol< 4-amino-1-naphthalenesulfonic acid< benzoic acid< sodium salt

2) water soluble: sodium salt, benzoic acid

Toulene soluble: antharcene, 4- amino-1-naphthalenesulfonic acid

Ligroin soluble: resorcinol

Answer 3

To determine the increasing order of polarity for the compounds listed, you can consider the functional groups present in each compound. Generally, polar compounds have functional groups like hydroxyl (-OH), carbonyl (C=O), and amino (-NH2). Nonpolar compounds have mostly carbon and hydrogen atoms.

Let's analyze each compound:

1. Resorcinol: It has two hydroxyl groups (-OH), indicating it is polar.
2. Anthracene: It consists of only carbon and hydrogen atoms, making it nonpolar.
3. Benzoic Acid: It contains a carboxyl group (-COOH), which makes it polar.
4. 4-Amino-1-naphthanesulfonic Acid, sodium salt: It contains both an amino group (-NH2) and a sulfonic acid group (-SO3H), making it highly polar.

So, the increasing order of polarity for the compounds is: Anthracene < Resorcinol < Benzoic Acid < 4-Amino-1-naphthanesulfonic Acid, sodium salt.

Next, let's predict which solvent might solubilize each solute:

1. Resorcinol: Since it is polar, it is likely to be soluble in polar solvents like water.
2. Anthracene: Being nonpolar, it is expected to dissolve in nonpolar solvents such as ligroin or toluene.
3. Benzoic Acid: Due to its polarity, it should be soluble in both polar (e.g., water) and organic solvents.
4. 4-Amino-1-naphthanesulfonic Acid, sodium salt: This compound is highly polar because of both amino and sulfonic acid groups. Therefore, it should be soluble in polar solvents like water.

To summarize:
- Resorcinol is soluble in water.
- Anthracene is soluble in nonpolar solvents like ligroin or toluene.
- Benzoic Acid is soluble in both polar and organic solvents.
- 4-Amino-1-naphthanesulfonic Acid, sodium salt is soluble in water.
