Hi,

For this proton transfer, why does the NH3 electron pair move to the H and not the electron pair from the Br?

Furthermore, when the substitution product bears a positive charge and also contains a proton bonded to O or N, the initial substitution
product readily loses a proton in a Brønsted-Lowry acid-base reaction, forming a neutral product.
