Label the nucleophile and the electrophile in the reactants. Show a detailed, stepwise mechanism for the FORWARD reaction. Use curved arrows to show the flow of electrons. To receive full credit, show all lone pairs. — H-N- NH + FB

Answer 1

In the above reaction lone pair of ammonia is donated to boron triflouride to form the product.

& A compound or ionic species which can accept an election to pair from a donor compound is called lewis aod. Concodes H. N-M + FB - HN H Here, Big accepts the election pars from NHtz hence, Biz is Lewis and 6 *A compound cohich donates the elecbon pas is called lewis Н base Here, NHg donates it's electron pair to Bf3 hence NH₃ is lewis base. -*: © HF: HN: + B-F: HN - B - 1 donation & :*- of election pair Mechanism of reaction
