Correctly classify each of the following compound as highly soluble or insoluble in water. 1. NaCl 2. CH3Cl 3. CH3OH 4. KOH 5. C
Anna35 [415]
There are solubility rules for inorganic compounds in water as shown in the picture attached. For organic compounds, we use the concept of polarity.

1. NaCl: Since NaCl is a chloride and Na is not included in the list of insoluble, therefore, NaCl is<em> </em><em>highly soluble</em>.

2. CH₃Cl: This compound is organic. Since the electonegativity between C and Cl is great, it tends to be polar. Because water is also polar, this is <em>highly soluble.</em>

3. CH₃OH: This is an alcohol. Alcohols with short chains of hydrocarbon are <em>highly soluble </em>in water because of hydrogen bonding (-OH).

4. KOH: From the table, KOH is <em>highly soluble</em>. In fact, this is a strong solid which readily dissociates in water.

5.  C₆H₆ is the benzene ring. This is a nonpolar molecule, so you would expect this to be<em> insoluble</em> with water.

6. C₆H₁₄ is hexane which is a long chain of hydrocarbons. Because there is no point of hydrogen bonding, this is nonpolar, and therefore,<em> insoluble</em> in water.

7. KNO₃ is <em>h</em><em>ighly soluble</em> because all nitrates are soluble.

8. CCl₄ is an organic compound. Individually, C-Cl bonds are polar. But because there are 4 of them, they cancel out. As a result, there is a balance of partial charges which makes it nonpolar. Thus, this is <em>insoluble in water</em>.

9. NaSO₄: from the table, this is <em>highly soluble</em>.

10. <span>CH</span>₃<span>CH</span>₂<span>OH: Although it is composed of the nonpolar hydrocarbon chain, the OH group is much stronger such that it is <em>highly soluble</em> in water.

11. CH</span>₂Cl₂: This is polar because there is an imbalance due to the C-H and C-Cl bonds. Thus, it is <em>highly soluble</em> in water.

12. CH₃COOH is a carboxylic acid which is even more soluble than alcohols. Thus, this is <em>highly soluble </em>in water.

When both –NH2 and –COOH replace hydrogen atoms on the same carbon atom, a(n) ____ is formed. a. amine c. carboxylic acid b. ami
Mice21 [21]

-NH_{2} represents amine functional group and COOH represents carboxylic acid functional group. When these both functional groups are substituted onto a single carbon atom, then amino acid is formed.

The organic compound consists of -NH_{2} functional group and COOH functional group with a side chain is said to be an amino acid.

A: amine group is -NH_{2}.

C: carboxylic acid  group is COOH

B: amino acid represents -NH_{2} functional group and COOH functional group which are substituted onto a single carbon atom.

D: carbohydrate:  the general formula of carbohydrate is (CH_{2} O)_{x}.

Hence, amino acid is the correct answer.
