Lipids
The heterogeneous classes of organic compounds that are not water-soluble but are dissolved in organic solvents that are non-polar in nature are termed lipids. They are a long chain of fatty acids and esters of alcohols. Lipids are generally seen in several plants, microorganisms, and animals. They are utilized as insulation, components of the cell membrane, hormones, and molecules for the storage of energy.
Glycerophospholipid
Glycerophospholipid is the most abundantly occuring phospholipids found in the biological membranes. Lipids include a group of organic compounds like fats, hormones, oils, waxes, vitamins etc. They are non-polar molecules and are insoluble in water. Lipids play an important role in biological systems. They are the building blocks of our cell membranes, store energy and are involved in signaling.
Structure Of Camphor
A terpene with the molecular formula of C10H16O is a waxy, white color solid known as camphor. It is flammable. It also possesses a very pungent taste and a strong odor. There are various sources for extracting camphor from natural products such as the wood of the tree of camphor laurel. Sublimation of wood and steam distillation are some of the methods involved in obtaining camphor.
Glycolipid In Organic Chemistry
Glycolipids are lipids that are an important class of organic compounds in chemistry that have simple to complex applications. They contain carbohydrates, fatty acids, sphingolipids or a glycerol group. In other words, they are the modifications of lipids like acylglycerols, prenols and ceramides. They are all part of a wider group of compounds known as glycoconjugates.
Diterpenoid
The terpenoid class includes diterpenoids, which are chemical compounds with 20 carbon atoms. They are made up of four isoprene units and are derived from geranylgeraniol, a C20 precursor. They have a C20H32 basic structure. These characteristics distinguish diterpenoids from simple terpenes, which have just 10 carbon atoms.
![In the laboratory, we examined a few nickel coordination compounds; however, we were only able to scratch the surface with regards to the coordination chemistry of nickel. Consider these other nickel coordination compounds.
a. The coordination compound potassium hexafluoronickelate (\(K_2[NiF_6]\)) has been synthesized and characterized. It is red in color. Use this information to calculate an approximate value of the octahedral field splitting energy for \(K_2[NiF_6]\). Report your answer in units of kJ/mol.
b. Predict the expected magnetic characteristics of potassium hexafluoronickelate (\(K_2[NiF_6]\)). Explain your answer.
c. The nickel coordination compound bis(\(P,P\)-dialkylphosphinic-\(N\)-ethylamidato-\(N,S\)) nickel sounds complicated, but it’s not too bad. The ligand \(P,P\)-dialkylphosphinic-\(N\)-ethylamidato-\(N,S\) (abbreviated SPR\(_2\)N\(^-\)) is a bidentate ligand that forms coordinate covalent bonds to a Lewis acidic metal through its sulfur and nitrogen Lewis basic atoms as shown below:
[Diagram of \(P,P\)-dialkylphosphinic-\(N\)-ethylamidato-\(N,S\) ligand structure]
- The diagram depicts the ligand SPR\(_2\)N\(^-\) with a phosphorus (P) atom bonded to two alkyl groups (R), a sulfur (S) atom, and a nitrogen (N) atom connected to an ethyl group. The ligand abbreviation SPR\(_2\)N\(^-\) is given where R = \(C(CH_3)_3\).
Ni(SPR\(_2\)N)\(_2\) is diamagnetic in the solid state. However, when Ni(SPR\(_2\)N)\(_2\) is dissolved in solution, it is paramagnetic. Given that the coordinate covalent bonds remain intact in both the solid state and dissolved forms, provide an explanation for what may be occurring that causes the change in magnetic properties.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ffba53fc5-f280-45c2-b123-0feb9eb35059%2F7c464763-3877-46d1-bfa5-9ece563c4159%2F4ixbrux_processed.jpeg&w=3840&q=75)
