Verified step by step guidance

Understand the concept of solubility: Solubility of fatty acids in water is influenced by the length of their hydrocarbon chains. Longer chains tend to be less soluble due to increased hydrophobic interactions.

Identify the options: The problem provides four fatty acids with different carbon chain lengths: 4, 12, 16, and 22 carbons.

Recall the relationship between chain length and solubility: As the carbon chain length increases, the solubility in water decreases because longer chains have more hydrophobic (water-repelling) interactions.

Compare the chain lengths: Among the given options, the 22-carbon fatty acid has the longest chain, making it the least soluble in water.

Conclude based on the comparison: The 22-carbon fatty acid is expected to be the least soluble in water due to its long hydrophobic chain.
