Trimethylamine, (CH3)3N, is a common reagent. It interacts readily with diborane gas, B₂H6. The latter dissociates to BH3 and this forms a complex with the amine, (CH3)3N→BH3. The reaction between trimethylamine and borane is shown. CH3 CH3 H CH3-N : + B-H CH3-N B-H CH3 H CH3 H Is the BH3 fragment a Lewis acid or a Lewis base? To decide this, answer the following questions: H a Which of the following is a definition of a Lewis acid? proton donor electron pair acceptor proton acceptor electron pair donor
