There are four different esters with the molecular formula C4H8O2. Draw out each of these structural isomers and explain briefly how they could be distinguished by 1H NMR alone. Provide a sketch of what you predict the NMR spectrum of each compound would look like. Be as specific as possible, indicating both multiplicities and integrations.

There are two isomers which both have the molecular formula C_2H_6O. Write the structural formula for each which shows all the H's (not line - angle) based on the observed chemical shifts in the NMR spectrum. Isomer B has all 6 H's with delta=3.4 Match each substance in the left column with its description in the right column. Aromatic compound adds one H_2O to a triple bond to make an enol Ether adds H_20 to a double bond
