Question

The silver salt of a fatty acid on refluxing with an alkyl halide gives an
A) Acids
B) Ester
C) Ether
D) Amine

Answer 1

We need to know that the fatty acids are nothing but the salts of long-chain carboxylic acid. Free fatty acids are less soluble when compared to the salts of potassium or sodium and they precipitated as soap scum. Also we know that haloalkanes are the compound in which one or more hydrogen atoms are replaced by halogen atoms such as fluorine, iodine, chlorine etc.

Complete step by step answer:
We must remember that the unsaturated fat, significant part of lipids (fat-dissolvable segments of living cells) in plants, creatures, and microorganisms. By and large, an unsaturated fat comprises of a straight chain of a significantly number of carbon iotas, with hydrogen particles along the length of the chain and toward one side of the chain and a carboxyl gathering $\left( { - COOH} \right)$ at the opposite end. It is that carboxyl gathering that makes it an acid (carboxylic acid). In the event that the carbon-to-carbon securities are altogether single, the acid is immersed; if any of the securities is twofold or triple, the acid is unsaturated and is more responsive. A couple of unsaturated fats have expanded chains; others contain ring structures (e.g., prostaglandins). Unsaturated fats are not found in a free state in nature; regularly they exist in a blend with glycerol liquor) as fatty oil.
Refluxing silver salts of a fatty acid with alkyl halide yields ester. Hence option B is correct.
The reaction is as follows,
$C{H_3}COOAg + Br{C_2}{H_5} \to C{H_3}COO{C_2}{H_5} + AgBr$

Note:
As we know that the unsaturated fats have a wide scope of business applications. For instance, they are utilized not just in the creation of various food items yet in addition to cleansers, cleansers, and beauty care products. Cleansers are the sodium and potassium salts of unsaturated fats. Some skin health management items contain unsaturated fats, which can help keep up solid skin appearance and capacity. Unsaturated fats, especially omega-3 unsaturated fats, are additionally regularly sold as dietary enhancements.
