2-pentanol is CH3CH2CH2CH(OH)CH3
As can be seen it has protons in 6 different environments because H attached to no two carbon atoms are identically placed
the number 3
It's around 7-8 ppm.

The general types of chemical reactions are:- synthesis- decomposition- single replacement- double replacement
There is a vast amount of chemical processes involved in forensics, it all depends on what it is you rare testing and what you need to find out. Techniques include: * Gas chromatography - separates a compound into is constituents i.e. fire accelerants * High performance liquid chromatography - also separates compounds, can be used for drug analysis * Polarography - can test for the presence of heavy metals in liquids * Raman Spectroscopy - can be used for ink and paint analysis * Fourier Transform Infrared Spectroscopy - can be used for anything from drug analysis to paint analysis * Flame Absorption Atomic Spectroscopy - can be used to detect metal ions in mixtures
the number 3
mass spectrometry, also called mass spectroscopy, analytic technique by which chemical substances are identified by the sorting of gaseous ions in electric and magnetic fields according to their mass-to-charge ratios.
You think probable to optical spectroscopy.
The purpose of stellar spectroscopy is to determine the chemical composition of stars, the temperature and some other characteristcs..

Yes, they are classified by element or chemical composition.
IR spectroscopy works by using infrared beams to work out the structure of a chemical. The chemical is placed in an inert substance, e.g. Potassium Bromide. The refraction of the beams brings up a characteristic trace of the mystery compound, which can then be used to work out the structure.
Everything. About the only thing they have in common is "you learn about them in analytical chemistry class."Except "Nuclear Mass Resonance Spectroscopy", which doesn't exist and I assume is an error that should have read "Nuclear Magnetic Resonance Spectroscopy".X-Ray spectroscopy gives you the conformation in a fairly direct (okay, it's actually not all that direct) manner.NMR spectroscopy mainly gives you chemical structure information; you can finesse it a bit (NOESY and related techniques) to give some conformational information.Mass spectroscopy is pretty much chemical structure only (and, again, it's not all that direct, it just tells you what fragments the molecule breaks apart into; figuring out how they fit together is your problem).
