Whereas nech group doesn't exist. However, organic chemists usually refer to a lewis acid as an electrophile (which is electron poor), and a lewis base as a nucleophile (electron rich). So, if you have a compound with two electrons, you should look at where the two electrons are rather than where they were.
There are 3 steps to solve this one. The pair of electrons in a mechanistic. Here’s the best way to solve it.
Show transcribed image text there’s just one step to solve this. Start with the group containing the two electrons and work your. Lich, cooh, hbr are electron rich groups. Your solution’s ready to go!
Identify the charge on the atoms in each compound to determine their electronic nature.
