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 underline or circle the answer please and thank you!)
