Trimethylamine weak base
WebThe chemical formula of caffeine is C8H10N4O2. One way to determine the predominant species at equilibrium for an acid-base reaction is to say that the reaction arrow points to the acid with the higher value of pKa. For example, Explain why this rule works. Trimethylamine, (CH3)3N, reacts readily with diborane, B2H6. WebApr 18, 2024 · Similarly, the same table lists trimethylamine as having a pK a of 9.8 . Again, this is actually its pK a H. I can’t find an actual pK a value for trimethylamine, but I would guess that it is >40, since the conjugate base of trimethylamine is the carbanion (CH 3) …
