WebPropene. 43. Ethene. 44. Methane. approx. 60. For strengths of organic acids see E. P. Serjeant and B. Dempsey (eds.), Ionization Constants of Organic Acids in Solution, IUPAC Chemical Data Series No. 23, Pergamon Press, Oxford, UK, 1979. The strength of a base is related to the pK a of its conjugate acid as pK b = 14 - pK a.
