Lesson 8c— Nucleophiles and Electrophiles

A nucleophile is an electron-rich center with a non-bonding pair of electrons.

true

Nucleophilic attack is characterized by forming a new bond to hydrogen.

false

The worst leaving groups are the conjugate bases of strong acids.

false

Carbocations are more stable when they have a π-bond one bond away from the central atom bearing the positive charge.

true

In a proton transfer process, the nucleophile is a hydrogen atom, and it acts as an acid.

false

When a carbocation rearranges, H+ shifts to the positively-charged carbon and the charge relocates to a less highly-substituted carbon.
