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.

The answer to your question is:

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.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

it should be all of them because it asks if you included all of those in your answer
