text: The acid dissociation constant (pK a ) values of all alkanes are estimated to range from 50 to 70, depending on the extrapolation method, hence they are extremely weak acids that are practically inert to bases (see: carbon acids).
text: They are also extremely weak bases, undergoing no observable protonation in pure sulfuric acid (H 0 ~ –12), although superacids that are at least millions of times stronger have been known to protonate them to give hypercoordinate alkanium ions (see: methanium ion).
