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 seve…
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. Lipi…
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 …
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 lipid…
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 disting…

Chapter 15, Problem 15.46UTC
Interpretation Introduction

(a)

Interpretation:

To assign the oxidation number for each of the elements present in the given compound.

Concept Introduction:

Oxidation number or oxidation state of an atom in a molecule is the positive or the negative charge that an atom would have possessed if the compound would have been ionic. There are many rules for assigning the oxidation state to the given atom in a molecule. Some of them are :

  1. The oxidation state of Group 1 elements is taken to be +1.
  2. The oxidation state of Group 2 elements is taken to be +2.
  3. The oxidation state of oxygen is always -2 in most of the compounds except peroxides.
  4. Oxidation state of halogens is taken to be -1 usually.
  5. The oxidation state of hydrogen is taken to be -1 when bonded to metals and +1 when bonded to non-metals.
  6. Any element when present in its elemental form has zero oxidation state.
  7. The oxidation state of Fluorine is taken to be -1 except when present in elemental state (F2).
  8. The sum of oxidation states of all the atoms present in a given molecule is equal to zero.
  9. In case of ions, the sum of oxidation state is equal to the total charge carried by the polyatomic ion
