Answer 1

The chemical formula for octyne is C₈H₁₈.

Step-by-step explanation:

The chemical formula for octyne is C₈H₂. Alkynes are hydrocarbons that contain a triple bond. The general formula for alkynes with one triple bond is CnH2n-2. In the case of octyne, which has 8 carbon atoms, the formula would be C8H18.
