Consider 2-butylene versus 1,3-butadiene...

Explanation:

And so we gots....H3CCH=CHCH3 versus H2C=CHCH=CH2. The πbond of the former creature is LOCALIZED between C2 and C3...and of course this could give rise to 2 geometric isomers, which are?

The πbonds of the LATTER are delocalized over 4-centres...certainly addition of 1 equiv HX would give rise to 1,4addition to some extent....
