3.14. Using IR spectroscopy, how can you best differentiate between the following two compounds? OH OH А B a. Using the functional group region, you will see a broad band for compound B only. b. Using the functional group region you will see a band for a secondary hydroxyl group for compound A only. c. Using the fingerprint region, you will see a band for a secondary hydroxyl group for compound A only. d. Using the fingerprint region, you will see a difference between the two compounds, but must use the literature or a reference compound to make the final determination.
I really am struggling to explain how you could differentiate these two molecules, other than their amounts of carbons, I am just struggling with this question!
Given : Two Compounds 3-pentanol and 2-hexanol.
Four statements regarding IR spectroscopy.
To find: which statement is correct to differentiate two Compounds on the basis of IR spectroscopy.
Solution: IR spectroscopy stands for infra red spectroscopy. It is also called as vibrational spectroscopy.
IR spectroscopy is generally used to determine or identify the unknown compound mainly on the basis of presence of functional group. It has a chart of different values range for functional groups.
In IR spectroscopy, infra red light interacts with the given compound or the molecule.
In IR spectroscopy there comes a region which is very important that is called as fingerprint region. It ranges from 600-1400cm-1. Fingerprint region gives a clue regarding a particular compound or a molecule.
