Question “Which compound matches the IR spectrum? 1-hexen-3-ol 1-methylcyclopentene 3-hexanol 1.5-hoxadiene cylohexane trans-4-octene dipropyl ether Which compound…”

Answer

Infrared spectroscopy

At certain absorption frequencies, infrared bands are visible.

The function group determines the reduction in mass and spring constant for a bond. Higher frequency ranges are associated with stronger bonds with lighter atoms. Different functional groups give absorption bands at different intensities and ranges in IR. Knowing the absorption range allows you to predict the functional groups present in a given molecule. Below is a table that shows the IR absorption for common functional groups.

Because their bonds are polar, these groups absorb IR radiation. This causes the bonds to vibrate at a specific wavenumber. Different functional groups can then be identified in the IR spectra by using wave numbers.

Functional group	Absorption range
Alkane	2800-2900
Alcohol	3400-3600
Alkene	1640-1680 3020-3100
Alkyne	2100-2250 3300
Nitrile	2200-2250
Aromatics	1650-2000
Amines	3300-335
Carbonyls Aldehyde Ketone Ester Acid	1720-1690 1750-1680 1750-1735 1780-1710

Two bands are included in the IR spectrum.

Peak at HTMLmedia_tag_15$ signifies the Alkyl HTMLmedia_tag_16$ bond, and peak at HTMLmedia_tag_17$ signifies the alkyl HTMLmedia_tag_18$ bonds.
