Answer:

Both molecules are electron-precise, and are not considered to undergo resonance....

Explanation:

We gots the structural isomers, #"1-bromo-1-butene"#, i.e. #BrHC=CHCH_2CH_3#, and #"1-bromo-2-butene"#, #H_3C-C(Br)=CHCH_3# (and other isomers are available..)

#"1-bromo-2-butene"# can generate geometric isomerism. How?
