When thinking of E or Z, the first thing that comes to mind is the double bond of
the alkene. From there, you look at the atom attach to the double bond of the alkene. There are 4
atoms: 1) Carbon (top left) : bonded to 1 carbon and 2 hydrogen 2) Carbon (bottom left) : bonded
to 2 Oxygen [treat double bond here as two bonds] and 1 Hydrogen 3) Carbon (top right) :
bonded to 2 carbon and 1 hydrogen 4) Hydrogen (bottom right) : bonded to nothing. On each
side of the double bond, rank the priority (with respect to molecular mass) Bottom left >> Top
left Top right >> bottom right since the two groups are trans each other, this is an E isomer
