Question #1c217

Answer 1

`"n-butane"` DOES NOT generate any geometric isomers.......

Explanation:

And nor does `"isobutane"`, `"H"_3"CCH(CH"_3")CH"_3`.

However, `"2-butylene"` can generate cis and trans isomers as shown:

These are GEOMETRIC isomers, because the `C-C` connectivity is IDENTICAL for each isomer: `C1` connects to `C2`.........to `C4`. Their different geometry gives rise to different physical and chemical properties.
