IR analysis
the band at 1700 cm-1 is due to carbonyl group stretching
the band at 2981 cm-1 is due to aliphatic -CH stretching
the band at 3029 cm-1 is due to aromatic -CH stretching
the band at 3061 cm-1 is due to alkene CH stretching
the band at 1637 cm-1 is due to alkene C=C stretching
the band at 1449 and 1493 cm-1 is due aromatic C=C stretching
the band at around 1195 cm-1 is due to C-O stretching of ester group.
1H NMR analysis
the peak between 7 - 8 ppm is due to aromatic protons
the peak at 6.44 ppm is due to alkene CH proton
the quartet at 4.2 ppm is due to methylene proton of ethyl group
the triplet at 1.3 ppm is due to methyl proton of ethyl group.

Hello! I am in OCHEM 2 and im trying to figure out what my
unknown is. Based off my many tests, the unknown has multiple bonds
and a boiling point of 39-41 degrees celsius. Attached is the IR
and NMR. I think my unknown is 1-pentyne. The unknown I have has a
very pungent smell. The molecular formula is not given as the

I
determined this as the product of my aldol reaction I performed
with 4-methoxybenzaldehyde and 3'-methoxyacetophenone. It was
approved by my supervisor so I am pretty confident it is correct.
Looking at the IR spectra, there is a large broad peak at
~3300, which I know usually indicates alcohol or acids. There is no
alkyne or amine in the structure. What could account for this peak?
Is it just a spectrometry fluke or am I just missing something...
