Question

2.1 Bis (2,4,5-trifluorophenyl)methanone 6. IR (ATR, cm): 3142, 3093, 3070, 1661, 1627, 1513, 1437, 1423, 1335, 1298, 1233, 1213, 1185, 1143, 911, 889, 862, 796, 767, 716, 581; 'H NMR (90 MHz, CDC13) 6 7.56 (ddd, 2H), 6.98 (td, 2H). Figure 1. Physical appearance of the product, 6.

For the last picture: The values for the NMR are 7.59, 7.58, 7.57, 7.57, 7.55, 7.55, 7.55, 7.53, 7.25 (cdcl3), 7.01, 7.01, 7.00, 6.99, 6.98, 6.98, 6.97, 6.97, 6.96, 6.95. (from left to right). Also the values found for the IR and NMR are listed in the first picture. I need help figuring out their functional groups and why (preferably an explanation if you don't mind). Also I need help analyzing the TLC and find it's value.

I added the values from the last picture just in case if it's hard to see. But the first picture has all the signals already found from both IR and NMR Spectra I just need to know what functional group they belong to and why. I also need help analyzing the TLC.
