What does NDI stand for chemistry?
1.1 Introduction. 1,4,5,8-Naphthalenediimides (NDI) represent a class of aromatic compounds with an electron-deficient π-system whose electronic, redox and spectroscopic properties have led to their extensive study in the field of supramolecular and materials chemistry.
Which extra element is present in naphthalene?
naphthalene, the simplest of the fused or condensed ring hydrocarbon compounds composed of two benzene rings sharing two adjacent carbon atoms; chemical formula, C10H8.
How do you make naphthalene?
The method for the preparation of naphthalene dicarboxylic acid of the invention is conducted by the liquid-state oxidation reaction of dimethylnaphthalene with oxygen in air in the presence of acetic acid solvent using metal catalysts of cobalt and manganese, and using bromine as a reaction initiator, and it is …
What is NDI in finance?
First, let’s explain what Net Disposable Income (NDI) is. NDI is the amount of your monthly income that is left after you pay all of your monthly bills. Income – Expenses = NDI.
What are chemical properties of naphthalene?
Physical / Chemical Properties: Naphthalene is a white crystalline or colorless to brown solid. Naphthalene has a distinct aromatic odor. Vapor pressure1: 0.087 mmHg. Octanol-Water Partition Coefficient (log Kow)1: 3.29.
Is naphthalene an atom or molecule?
A naphthalene molecule can be viewed as the fusion of a pair of benzene rings. (In organic chemistry, rings are fused if they share two or more atoms.) As such, naphthalene is classified as a benzenoid polycyclic aromatic hydrocarbon (PAH).
Is naphthalene a molecule?
What is naphthalene balls in chemistry?
Naphthalene balls are obtained from coal tar. Coal tar is obtained by the distillation of coal. Naphthalene is an aromatic organic compound obtained from coal tar. Naphthalene is mainly used to kill fabric pests. Naphthalene balls are aromatic hydrocarbons.
Is naphthalene molecular or ionic?
Naphthalene is a covalent molecule, because it is only consists of carbon-hydrogen bonds, but it is not a complex molecule. Carbon and hydrogen are nonmetals with similar levels of electronegativity.
How is NDI calculated in finance?
NDI is the amount of your monthly income that is left after you pay all of your monthly bills. Income – Expenses = NDI. That’s oversimplified, though.
