Homework Answers
Complete molecular structure can't be predicted only from IR spectra but the functional groups present in the molecule can be predicted. To predict complete structure Mass spectra and NMR spectra should also be given.
Like in first graph we r getting a sharp peak at 1807 cm-1 which shows the presence of ester carbonyl group.
Also the graph shows two peaks one at 2937 and one at 3019 which shows the presence of SP³ C-H bond and SP² C-H bond respectively.
Now the second graph shows a peak at 1712 which shows the presence of carbonyl group and two peaks between 2800-2900 shows presence of aldehydic hydrogen.
