A non-branching ether has a molecular ion peak at m/z=102 and another significant peak at m/z=57. Draw the structure of the molecule. You do not need to show the hydrogen atoms, but you may want to place the carbon atoms in a zigzag pattern to make it easier to count how many you've drawn.

An unknown compound A has an empirical formula of c3h6o and a
molecular ion peak in its mass spectrum at m/z 116. It also has no
IR absorption at 3200-3600cm^-1 but shows a peak at 1740cm^-1. The
H NMR spectra data of A is given below in table format. Use this
information to answer questions a-d below.

charge)
label the molecular ion peak as "M+" (if present)
label major peaks other than the molecular ion with three
things:
1) the mass to charge ratio
2) the structure or formula for that charged fragment
3) another formula to show which fragment was lost by the molecular
ion to form that ion
