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.

can someone please tell me all the peaks bends etc in the
first IR as well as the functional groups. also interpret the nmr
please
