Question

What are examples of terminal alkynes?

Answer 1

Certainly a `"1-alkyne"` is a terminal alkyne....

Explanation:

For acetylene or propyne we have no choice, i.e. we gots `H-C-=CH` or `H_3C-C-=CH`, for `"butyne"`, we could have a terminal alkyne, a `"1-butyne"`, `HC-=C-CH_2CH_3` or `"2-butyne"`, `H_3C-C-=C-CH_3`. We would expect these isomers to have different physical and chemical properties.
