Can someone help with the analysis of this NMR spectrum for the
synthesis of benzyl methyl ether. (Benzyl chloride, diethyl ether
and then added sodium methoxide to produce benzyl methyl
ether)?
What I have so far is:
4 different protons:
3 x 1H on the benzene ring, doublet
2 x 1H on benzene ring, either side of O, doublet
2H on Carbon beside O, quartet
3H on end of alkene with O, triplet
I don't understand where they match up...
