Please fully annotate this IR spectrum in the picture below, no need to annotate the fingerprint region (400-1500 cm-1). Thank you so much!!

Consider isomeric alcohols A and B and mass spectra [1] and [2].(a) Label the molecular ion and base peak in each spectrum. (b) Use the fragmentation patterns to determine which mass spectrum corresponds to isomer A and which corresponds to isomer B.

please help me identify all the peaks?

HO The compoind molecular formula is characteristic peak of alcohols is a C4H100 and its molecular ion mass is peak (enter characteristic peak of alcohols) 74 amu. A Spring 24 (1) CHM 332 Organic Chemis

I need help to perdect the ir spectreum digram for the staring matrial  and also for it need to draw the staring matrial and labled the functional groups on it and on the ir spec digram  I linked an example I made on how it suppose to look, its not the answer just the format
