Organic Compound Analyzed using UV specro and IR Spectro

A organic compound is analyzed using UV-Specroscopy and IR spectrometry.

(A) assuming that this compound exhibits a maximum absorbance at a wavelength in the UV region, sketch an expected UV spectrum lable the axes.

(B) sketch an expected IR spectrum. Label the axes.

(C) What are the major differences and similarities between these two specra. Which is more usefull for quantitative work? and which is for qualitative?
