Please fix some of my wrong labeling Experimental IR spectrum of salicylic acid For all IR spectra: labelling of diagnostic peaks, written structure, and figure title explaining conditions of IR (i.e. KBr) and for what compound.)

THIS CAN NOT BE HAND - DRAWN Illustrate using a computer program the molecule from the molecular formula and interpret each of the following 1H NMR spectra.  The integration for each peak is given above the peak.  All spectra were taken from http://riodb01.ibase.aist.go.jp/sdbs/cgi-bin/direct_frame_top.cgi.

Why KBr used in IR spectroscopic sample preparation?  Please shortly answer at your own words. Answer should be to the point (Specific 2-3 lines).

Q6. Complete Table 6. i) Copy and paste (insert) the correct alternative of the structures below into the table, ii) insert expected number of different ¹H and 1³C environments expected for these compounds (Table 6: columns 2 and 3 respectively) and correctly label the ¹H and ¹³C NMR spectra below in boxes provided .CI CI Table 6: Assigning NMR spectra for aromatic Structures of disubstituted No. of expected ¹H NMR peak/s benzene compounds 1,2-dichorobenzene 1,3-dichorobenzene .CI 1,4-dichorobenzene CI compounds No. of expected ¹³℃ NMR peak/s
