2) For each of the following pairs of compounds, name one absorption band that can be used to distinguish between them. State what the bond is (bond order, between which 2 atoms), and approximately where it appears in the IR spectrum (in cm ¹). b) HO 1-hexanol OH phenol H₂N 1-butanamine ethyl acetate cyclohexane OH hexanoic acid LOH cyclohexanol NH₂ butanamide diethyl ether cyclohexene

Comparison of specific functional group diagnostic peaks (C=O carboxylic acid, C-H, O-H carboxylic acid, O-H phenol, C=C) between Literature and Experimental spectra.

Butanal and methylpropanal give slightly different mass spectra. Both give a molecular ion peak at m/z = 72, but butanal gives four other peaks whereas methylpropanal only gives three. State the species responsible for the four other peaks in the mass spectrum of butanal and write equations to show their formation from the molecular ion.
