I need help with my chem lab report.
I need to identify the unknown structure.
Please help me identify the importance of each peak in the
spectrums.
What would the reactions look like for this structure when it
reacts with ethanol for DNPH test, CrO3 and dioxane and NaOH for
iodoform test.
The compound was a clear liquid. It is insoluble in water. tests
positive for DNPH test, positive for CrO3 test and negative for
iodoform. These results tell me...
I need to use chem draw to draw these compounds and
paste it on my lab report. Can you please draw these compounds in a
simpler way amd name them as well ?

Hi I need help plotting this graph from my thin lenses lab. They want me to pick two sets of points from my data. The first set will become p1 and q1 and the second set will become p2 and q2. Plot q1 and p1, and q2 and p2 on the same graph. (Hint: select values of p1 and p2 such that the difference between them is at least 30cm.) I'm using this to find the the intersection of the...
