which of the molecules below is propyne? mark this and return

Answer

Explanation:

Step1: Recall propyne structure

Propyne has the formula $C_3H_4$ and contains a carbon - carbon triple bond with the structure $HC\equiv C - CH_3$.

Step2: Analyze given structures

The first two structures have carbon - carbon double bonds ($C = C$) and are alkenes. The third structure has a carbon - carbon triple bond and is propyne.

Answer:

The third structure (the one with a carbon - carbon triple bond) is propyne.
