Solution Steps

Step 1: Identify the Functional Group

The molecule has an -SH group attached to a carbon chain. This functional group is called a sulfhydryl group, characteristic of thiols.

Step 2: Relate Functional Group to Properties

Thiols are similar to alcohols but contain sulfur instead of oxygen. The S-H bond is weaker than the O-H bond in alcohols, making thiols slightly acidic. The sulfhydryl group can also participate in hydrogen bonding with water, increasing the solubility of molecules containing it.

Step 3: Match Properties to Given Options

The provided options that best describe the behavior of a molecule with a sulfhydryl group are that it acts as a weak acid and makes molecules more soluble in water.

Final Answer

It acts as a weak acid and makes molecules more soluble in water.
