how is that impossible?  :o
peak area is just 3:2:3 - the number of H bonded to the carbon
H-atoms in the neighbouring is 2:3:0 -the last one is 0 because it is bonded to an ester
number of splits are 3:4:0

hope that helped!

When i did it, i came to the conclusion that the question is ambigious/stupid. i.e. "splits" is ambigious.

I put one split for the -CH3 part until I later on in the exam I saw the term "no splitting" so I went back and changed it.

I agree, I was thinking do they want total number of peaks in the end (in high res NMR) or do they want to know how many peaks each single peak will split into.
