Question

Rank these compounds from most soluble in water to least soluble in water.

1) HOOC(CH2)5COOH
2) HOOCCOOH
3) CH3(CH2)5COOH
And which of the following statements is true?
1) Larger compounds can form more hydrogen bonds than smaller compounds with similar structures.
2) Compounds that can form more hydrogen bonds are more soluble in water.
3) Smaller compounds are generally more soluble in water than larger compounds with similar structures.

Answer 1

The answer to your question is:

Step-by-step explanation:

The rank is:

1) HOOCCOOH

2) HOOC(CH2)5COOH

3) CH3(CH2)5COOH

The statements that are true are in bold.

1) Larger compounds can form more hydrogen bonds than smaller compounds with similar structures. This is incorrect the larger the compounds, the less hydrogen bonds they can form.

2) Compounds that can form more hydrogen bonds are more soluble in water. This statement is true, compounds that form hydrogens bonds can interact with water.

3) Smaller compounds are generally more soluble in water than larger compounds with similar structures. This option is true because the smaller the molecules the more hydrophilic they are.
