Draw the structure of each of the following fatty acids, and give the structure its common name. (a) $n$ -Dodecanate
(b) $c i s-\Delta^{9}$ -Hexadecenoate
(c) $c i s, c i s-\Delta^{9}, \Delta^{12}$ - Octadecadienoate

Structure 1- dodecanoic acid (lauric acid)

Structure 2- hexadecanoic acid (palmitic acid)

Structure 3- octadecanoic acid (stearatic acid)

Explanation:

Fatty acids are  carboxylic acids having long aliphatic chain. The chain may be either saturated or unsaturated. There are many naturally occurring fatty acids having unbranched chain of an even number of carbon atoms.

Usually, the common name of the fatty acid is not related to its systematic name. Its systematic name is obtained by IUPAC nomenclature.

The images shown are the skeletal structures of lauric acid, palmitic acid and stearic acid. I have written the names of the acids because the question specifically mentions that the compounds are fatty acids and not their salts.

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.

explanation:

did anyone actually do this? like if anyone has submitted this i rly need .
