the peak you write at 1642 cm-1 is not for Alkene its for the
carbonyl (CO) group because if its C=C there is a stretch at around
3040-3050 cm-1 which is for =C-H stretch. so, the functional group
present is CO group.
peak at 2969 cm-1 is correct its for the C-H stretch.
region below 1500 cm-1 is for the fingerprint region.
most important peak is the peak for CO group.
how do you find the functional groups for this IR spectrum result? this is for my...
Can anyone identify the major peaks in this IR spectrum that determine important functional groups? It is supposed to be of Eugenol (isolated in lab from ground cloves).
From the IR spectrum shown below, suggest functional groups that you recognized, and with the peak (wave number, 1/cm group test you would use. also suggest which functional INFRARED SPECTRUM Transmitance 3000 2000 1000

Label the IR spectrum for functional groups and identify the correct structure of the compound. Indicate the peaks on the H1-NMR to show carbon connectivity and splitting pattern. Calculate the degree of unsaturation. Draw the correct structure of the compound. 2) Mol wt: 148 g/mol IR spectrum: H1-NMR: 5 H 10 11 ppm 2H 2.H
In my Organic Chemistry class I was asked by my professor to identify functional groups in Vitamin B6? I need help with this. Thanks!

For organic chemistry IR lab, please answer with an explanation! 1. How is infrared (IR) light produced for the infrared experiment? 2. What structural features are visible using the IR experiment? Why are these structure features visible with IR light? 3. Why is it necessary to dry your sample before IR analysis? 4. Some functional groups give a weak or no signal with IR. What are some bonds not visible by IR spectroscopy? Give at least one example of a functional group not visible by...
