Question

What would the molecule below be classified as?

alkane

alkene

saturated hydrocarbon

unsaturated hydrocarbon

Answer 1

Consider,

An alkene has double bonds, and alkane only has single bonds. This has a triple bond, and it's therefore an alkyne.

It isn't saturated, because the triple bond stops the two `sp` carbons from being saturated with hydrogens.

Hence, this may be an `"unsaturated hydrocarbon"`.
