2butene can have two geometric isomers. I don't know whether you're wrong or not.

Explanation:

The methyl groups pendant to the double bond, to the olefin, can be on the same side (the cis isomer), or on opposite sides (the trans isomer). These are geometric isomers that are distinct molecules with distinct properties (e.g. m.p. trans,106C;cis,139C).
