Homework Answers
peak around 1700 cm-1 is due
to aldehyde carbonyl functional group.
And peak around 3000 cm-1 is due to C-H of Alkane functional group.

You have an unknown compound with an IR peak at 3050, and a broad peak at 3300. After leaving this compound in an open vial and in the sun for three months the peak at 3050 has decreased slightly, and the peak at 3300 is replaced by a strong narrow peak at 1700. What kind of compound did originally have? (Functional group is enough) enol, ketone , an alcohol or phenol (between these 4 options which one is it? clearly...

i have some questions about IR. my first one being I am anaylyzing an IR graph what are reasons for the frequency not lining up with literature values? secondly, why might an alkyl CH group not show up at all on an IR graph? and lastly, what do the different peak lengths mean? and why can you look at the same compound but on different graphs and have different peak lengths?

Does a stronger peak in IR means anything? For example, I have an IR and is looking at 2 different peaks to see which one is the major product and minor product. Does stronger peak (deeper toward the bottom) mean more major product? or no? i.e. can you tell if a product is a major or minor product from looking at IR?

What IR stretch would indicate you have a product that did not undergo a hydride shift? O A sharp peak in the range of 880 - 900 cm-1 A strong peak in the 1000 - 1255 cm-1 A sharp peak in the range 3250 - 3325 cm-1 A broad peak in the range of 3200 - 3525 cm-1

2. (2 pts.) Provided below are IR spectra of 1,2,3,6-tetrahydrobenzaldehyde (I) and 3-methyl-2-cyclohexen-1-one (II). Decide which of the IR spectra A and B corresponds to which structure (I or II). On each spectrum, identify the peaks that are associated with a specific bond vibration bond by drawing the functional group for that bond, circling the specific vibrating bond and drawing an arrow from the circled bond to the absorption peak, as appropriate. Include all the C-H bonds. odo and II...
