Is the following alkene E or Z?

To figure out E or Z we separate the double bond in two halves. We, then, look at each carbon from the double bond and the two groups it is attached to. We go atom by atom until we find a difference. Whichever atom has a bigger atom numbers wins and gets circled.


The carbon on the left is attached to a hydrogen and a carbon. Carbon wins because it has a bigger atom number on the Periodic Table and we circle it. Carbon on the right is attached to a fluorine and a carbon. Fluorine wins because it has a bigger atomic number.

The two circled groups are on the opposite side of the double bond and will have E configuration.
