Verified step by step guidance

Understand the structure and properties of waxes: Waxes are esters formed from long-chain fatty acids and long-chain alcohols. This structural composition gives them certain physical and chemical properties.

Consider the solubility of waxes: Due to their long hydrocarbon chains, waxes are generally nonpolar and hydrophobic, making them insoluble in water. This is a key characteristic of waxes.

Evaluate the melting point of waxes: Waxes typically have melting points above room temperature, which is why they are solid at ambient conditions. This property is due to the long carbon chains that require more energy to break intermolecular forces.

Assess the biological function of waxes: Waxes serve as protective coatings in nature, helping to prevent dehydration and protect against parasites. This is observed in plants and animals where waxes form barriers.

Identify the false statement: Given the properties and functions of waxes, the statement that waxes are soluble in water is false. Waxes are hydrophobic and do not dissolve in water.
