The name butane is applied by IUPAC to the unbranched form of B4H10.

However many chemists use the name butane to refer to both isomers of

B4H10 , n-butane the unbranched form and iso-butane the branched form.

when we draw the structure of 2 butene it has double bond and also has different groups 1butene has double bond too but has identical groups which not saticfy conditions of geometric isomerism

In 2-butene the double bond is in the second position, C-C=C-C. The two carbon atoms attached to the double bonded C atoms (numbering left to right C1 and C4 may be on the same side of the double bond, "cis" or opposite "trans")

In 1- butene there is no difference.

See the picture in wikipedia butene article, a picture is a lot easier to understand.

I'm guessing it's because butane is an alkane, which means it only consists of single bonds, so you can't form a geometric isomer because it will be the isomer no matter how you change it.
