The first member of the alkyne homologous series' is
Correct answer: A. Ethyne
- A. Ethyne
- B. Methane
- C. Propyne
- D. Butyne
Explanation
The correct answer is Ethyne, which is the simplest molecule in the alkyne homologous series with the general formula CnH2n-2. Methane, Propyne, and Butyne are not the correct answers as they do not adhere to the general formula for alkynes and are structurally more complex.
