Determine if ethane (C₂H₆) is a stable or unstable acid and predict whether it will participate in an acid-base reaction (pK_a C₂H₆ = 50).

• A. Ethane is an unstable acid and will participate in acid-base reactions.
• B. Ethane is a stable acid and will participate in acid-base reactions.
• C. Ethane is an unstable acid and is not likely to participate in acid-base reactions.
• D. Ethane is a stable acid and is not likely to participate in acid-base reactions. 

Answer: (D)
