#2-"butene"# 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," -106 ""^@ C; "cis," -139 ""^@ C#).
