Answer:
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.
Answer:
The electron configuration for Iron (Fe) with 26 electrons is as follows 1s²2s²2p⁶3s²3p⁶4s²3d⁶ (the superscripts add up to 26) or the Noble gas [Ar] 4s²3d⁶
Explanation:
The subshells fill up in the order 1s, 2s,2p, 3s,3p,4s,3d... (etc) the subshells have the following number of e⁻ (electrons) s: 2, p:6, d:10, f:14. I attached the subshell levels and where to find them on the periodic table that I made when I taught this to myself after lecture. You can use the noble gas from the previous row to make this simpler to write.
