using the IR, the 13C, and DEPT NMR spectra of your product determine the identity of your unknown ester from a C-4 or C-5 alcohol. the identity of the C-4 or C-5 alcohol also needs to be determined. The following C-4 or C-5 alcohols will be used in this experiment: 1-butanol (n-butyl alcohol) 2-butanol (sec-butyl alcohol) 2-methyl-1-propanol (isobutyl alcohol) 3-methyl-1-butanol (isopentyl alcohol) 1-pentanol (n-pentyl alcohol) 2-pentanol 3-pentanol cyclopentanol Questions: 1. Why is the mixture extracted with aqueous sodium bicarbonate solution?...
report 13 C NMR, DEPT, observed bp. Evidence should be given that shows the reaction yeilded an ester product. Specific evidenceshould be given to support the identification of the product ester and starting alcohol. find the starting alcohol and state product ester Compare the IR spectrum to the IR spectrum of the starting material. Assign all the major peaks above the fingerprint region in your IR spectra. Assign the signals in the carbon and Dept NMR spectra. what evidence do...

Explain why the IR corresponds to a particular compound of those that are possible based on BP and why it couldn't be any of the others -mention at least 3 IR peaks that are present that correspond to functional groups in your molecule, and discuss specific peaks that were either present or absent that allowed you to rule out the other compounds possible based on the boiling point. Reference your IR spectra as figures. the boiling point for unkown 2:...
You react acetic acid with an unknown alcohol, and obtain the following NMR of the product What is the unknown alcohol? 1-butanol (CH3CH2CH2CH2OH) 2-propanol (CH3)2CHOH) 2-methyl-1-propanol ((CH3)2CHCH2OH) 1-propanol (CH3CH2CH2OH) 2-butanol (CH3CHOHCH2OHCH2)
Hi I just need a little help breaking down some information. I have an unknown, which i distilled on a microscale. The boiling point I got was 102 C. I performed a DNPH test which came back negative so its not an aldehyde or ketone, also a chromic acid was positive for a primary or secondary alcohol, and potassium permanganate negative for alkene or alkyne. My IR came back with 3 sp3 C-H peaks an O-H and C-O. The possible...
