Question

please answer all the parts

1.) For each molecule below indicate how IR and H NMR may be used to identify the molecule specific). 2.) For each circled hydrogen above indicate what multiplicity would be observed and draw the shape of the peak. 3.) Indicate which position would be brominated most effectively and draw the structure of the product from the radical bromination reaction
