Question

I need help assigning peaks in this spectrum for the listed product. I was told the following but can't figure out which is which. Can someone check and show me which is which?

I was told 3.9 is th ch3 next to O

6.9 is CH para to OCH3 in ring

4.1 is ch2 next to Alkene

7.3 is Ch aromatic between CH

However I couldn't figure out what that meant and it seemed like it was missing a peak. Can someone help and show me which peak is which hydrogen?

Thanks
