The samples included carbons with increasing level of graphitic order: three chars derived from two bituminous coals and a lignite, a synthetic carbon and a graphitized coke. The experimental characterization allows to classify the materials according to different structural parameters, including porosity,...
Re: How to Calculate NMR Signals «Reply #5 on:December 05, 2010, 12:11:42 AM » One way you can look at 16 based on your assumption of 4 is counting how many carbons away those "1's" are. This isn't a terribly good method...but an explanation at least. The 1's on the...

In pharmacy, the isomerism shown by the structure provides a way to distinguish the two drugs. For instance, the effect of dextroamphetamine and amphetamine in the body of a human is different. Answer and Explanation: Given molecule is Bromo-toluene Bromo-toluene is a mo...

The stereoisomer count of a molecule can be predicted from its atomic connectivity by identifying the chiral centers. Stereoisomerism has been used in drugs and chemical laboratories to synthesize new chemicals and medicine. Answer and Explanation:1 ...
Frankly, I'm at a bit of a loss for peaks for every single carbon. On our practice NMR sheets we are given the molecular formula, but not the structure. So I don't see how its possible to look at the spectrum and say, oh, there are 5 carbons. We also usually get nicely circled...
Functional groups can show up on all sorts of carbon chains. But if the focus of our discussion is a functional group, we don’t want to get distracted by all of the carbons, hydrogens, or anything else in the parent chain. Instead, wereplacethe entire parent chain with the letter R ...
a magnetic dipole bond Given the following Lewis structure: 1. How many unshared pairs of electrons are present in this molecule? A) 0 B) 1 C) 2 D) 3 E) 4 2. How many electrons are shared between carbons 1 and 2? How many valence electrons remain in...
Water Hardness in mg/L = Water Hardness in PPM Water Hardness Measurements mg/L = milligrams (of minerals) per liter of water = a hardness measurement where 1 mg/L = 1 PPM of minerals in the water source. PPM = parts per million, in this case "parts" refers to parts of hard wa...
