Waxes have long fatty acid chains connected to monohydroxy alcohols via ester linkages.

• A. long fatty acid chains connected to monohydroxy alcohols via ester linkages
• B. short fatty acid chains linked via dihydroxy alcohols via ether linkages
• C. long fatty acid chains connected to mono-hydroxy alcohols via glycosidic bonds
• D. branched hydrocarbons connected to polyhydroxy alcohols via amide bonds

Answer: (A)

Waxes are esters formed from a fatty acid and a long-chain alcohol. The key feature is the ester bond that links the carboxyl group of the fatty acid to the hydroxyl group of a mono-hydroxy (single OH) alcohol. This combination gives molecules with long hydrocarbon tails on both sides, contributing to their hydrophobic, waxy character.

So the description that fits best is long fatty acid chains connected to mono-hydroxy alcohols via ester linkages. The other options describe different bond types or components (ether bonds, glycosidic bonds, or amide bonds) that do not define wax structure.
