Describe the significant IR signals that are present or absent and determine what chemical it could be representative of.
There is a strong peak around 1700 cm-1
it is well known that any compound having a carbonyl bond (C=O) shows strong IR peak in between 1670-1820 cm-1
So, this compound must has an carbonyl group ( may be acid or ester or ketone or aldehyde)
there are more than two peaks in between 1000 to 1300 cm-1
which are mainly due to C-O stretch. hence, the compound has both carbonyl group and C-O group, therefore, the compound must be an ester compound.
there is no peak of medium intensity between 1400 -1600 cm-1 , which concludes that the compound does not have any aromatic C=C bond. similarly there is no variable peak in between 1400 - 1680 cm-1 or in between 2100-2380 cm-1. So, it has no C=C or alkyne bond. It is an alkane having ester group. The peak at 3000 cm-1 due to the C-H stretch.

What IR Spectra is this?
The options are: Acetamide, Benzoic Acid, Benzophenone,
p-Aminobenzoic Acid, and Triphenyl Methanol
1% 4000 3500 3000 2500 2000 1500 1000 650 cm-1
Please evaluate the IR spectrum. Provide a structure and note
any important peaks corresponding to the structure.
It was an experiment using:
isoamyl alcohol + acetic acid
sulfuric acid as the catalyst
and the products are isoamyl acetate and water. Thank you so
much!!!
