ABSTRACT

Br+ : the bromine positive ion has only six electrons and thus has an empty p-orbital.

6. Full-octet electrophiles in which an empty orbital becomes available during a reaction: In many cases, an electrophile (such as carbon) starts out in a reaction step with a complete bonding octet; the electrophilic atom cannot accept an electron pair in this condition due to the lack of an available orbital in which to place the electrons.
