Question

Wax is an ester of fatty acid?
A. Long chain of dihydric alcohol
B. Long chain of trihydric alcohol
C. Long chain of monohydric alcohol
D. Short chain of monohydric alcohol

Answer 1

Hint: Fatty acid, a significant segment of lipids (fat-solvent parts of living cells) in plants, creatures, and microorganisms. For the most part, a fatty acid comprises a straight chain of a much larger no. of carbon, with hydrogen molecules along the length of the chain and toward one side of the chain and a carboxyl gathering (―COOH) at the opposite end. It is that carboxyl gathering that makes it an acid (carboxylic acid).

Complete answer:
Wax is an ester of fatty acids with long-chain monohydric alcohol. Cholesterol is the sort of alcohol found in wax. It isn't handily hydrolyzed like fat. It gives security. It forestalls unreasonable drying. It additionally gives water opposition. Beeswax, carnauba wax are instances of wax. Thus, the right answer is C. Waxes are an assorted class of natural intensifies that are lipophilic, moldable solids close to encompassing temperatures. They incorporate higher alkanes and lipids, ordinarily with softening focuses above around 40 °C (104 °F), dissolving to give low consistency fluids.
Hence, option (C) is correct.

Note: Waxes are insoluble in water however dissolvable in natural, nonpolar solvents. Characteristic waxes of various sorts are delivered by plants and creatures and happen in petroleum. Waxes are essentially burned-through modernly as parts of complex definitions, frequently for coatings. The fundamental utilization of polyethylene and polypropylene waxes is in the plan of colorants for plastics. Waxes give tangling impacts and wear protection from paints. Polyethylene waxes are joined into inks as scatterings to diminish contact. They are utilized as delivery operators, discover use as slip specialists in the furniture, and present consumption obstruction.
