Question

Which compound matches the IR spectrum?

Answer 1

From the above given IR spectra, it is evidently provided information regarding the presence of functional groups in molecule.

No peaks at about 3300 cm-1, tells us no -OH group in molecule. It is violated 1-hexene-3-ol and 3-hexanol.

No peak at about 3000 cm-1, gives information about absence of presence of double bond. It is violated 1-methylcyclopentene, 1,5-hexadiene, trans-4-octene.

Moreover, it shows C-O-C stretching frequency about 1300-1000cm-1. excluded cyclohexane.

So, finally the compound is di-n-propylether.

the reported spectra,

DI-n-PROPYL ETHER INFRARED SPECTRUM 0.8 0.6F 0.4 0.2 3000 2000 1000 Wavenumber (cm-1) NIST Chemistry WebBook (https://webbook.nist.gov/chemistry)
