*If the molecule contains Carbonyl group there should be a strong band bw 1700-1740cm^1
* A broad band bw 2500- 3500 cm ^-indicates presence of -OH group .
But in given problem no thiese bads are present .
So the spectra must corresponds to toluene option 3
3028 cm^-1(Sharp medium) - aromatic C-H frequency
1604 and 1495(Sharp medium) - presence of Carbon carbon double bond

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
unknown is not given. A list of 35 possible unknowns are given.

Which of the following statements about the ordinary IR
spectroscopic regions are TRUE?
True False In general, the energy carried by a photon of
IR radiation is greater than radiation is greater than the energy
carried by a photon of UV radiation.
True False Ordinarily we sense most IR frequencies as
colors in the region we call yellow.
True False We can sense some of the frequencies of the
FUNDAMENTAL region of the IR as heat.
True False In general, the IR FUNDAMENTAL region...
