What alcohol IR spectrum is that when reacted with acetic acid UNKNOWN D PPM 112 1-butanol...
Finding the structure of the ester from the following
ir peaks.
This experiment was performed by taking an unknown
alcohol;
1-butanol
2-butanol
3-methyl-1-propanol
cyclopentanol
1-pentanol
2-pentanol
3-pentanol
3-methyl-1-butanol
and acetic acid. to prepare the ester.
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?...
You react acetic acid with an unknown alcohol, and obtain the
following NMR of the product. What is the unknown alcohol?
Question 3 2 pts You react acetic acid with an unknown alcohol, and obtain the following NMR of the product. What is the unknown alcohol? 12.00 13.00 ppm (11) 3 ] 2.00 1- 3.00 0.0 4.0 ppm (11) 2-propanol (CH3)2CHOH) 1-propanol (CH3CH2CH2OH) 2-methyl-1-propanol (CH3)2CHCH2OH) 1-butanol (CH3CH2CH2CH2OH) 2-butanol (CH3CHOHCH2OHCH3)
Which mechanism gives you this NMR spectrum and what is the name
of it?
Acetic acid + 1-pentanol
Acetic acid + 2-pentanol
Acetic acid + isopentyl alcohol
Acetic acid + hexyl alcohol
Acetic acid + 4-methyl-2-pentanol
Also, please label the structure's Hydrogens as (Ha,Hb,Hc,Hd
etc)
Thanks!

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.
