Question

Waxes are esters of long chain fatty acids with long chain of:

• A. monohydric alcohols
• B. dihydric alcohols
• C. trihydric alcohols
• D. all of the above

Answer 1

The correct option is A monohydric alcohols

Waxes are esters of long-chain fatty acids $\left(C_{14}\right)-C_{36}$ with a long chain of monohydric alcohols $\left(C_{16}\right)-C_{36}$.
They are homolipids or simple lipids.

For example, Spermaceti is a palmitic acid ester of cetyl alcohol.
Its molecular formula is $C_{25}{H}_{51}COO{C}_{16}{H}_{33}$.
