1.Which pathway and what reagents are would be necessary to form each product (b) Draw out a step by step mechanism to show how each product was

1.Which pathway and what reagents  are would be necessary to form each product (b) Draw out a step by step mechanism to show how each product was formed (c)which product forms with the mass spectrum (d) draw the structures of the fragments responsible for the base peak of the mechanism to show how they form

2.(a) Identify five different absorption values in the infrared spectrum that could be used to differentiate the two isomers shown. (b) How many signals would be observed in the 1H NMR spectrum for each molecule?
