Can you please explain these two organic chemistry

questions dealing with IR spectroscopy peaks that can tell what products are formed based on starting material and reaction mechanisms with major and minor products? How do you know which product should be the major product and which one should be the minor?

14 ) Using infrared ( R ) spectroscopy , what peaks could you use to determine if product B or c ( Question
3 ) is forming from starting material A ? HO
