In the previous episode we discussed what happens when we use electrophilic aromatic substitution to add a group to a benzene ring, but what happens when you try to add even more groups? Well, things get a little more complicated. In...

Hyperconjugation plays a significant role in stabilizing carbocations, where adjacent alkyl groups donate electron density via sigma bonds to the positively charged carbon, spreading the charge and increasing stability.

Hyperconjugation involves the delocalization of electrons from a sigma bond (usually C-H) to an adjacent empty or partially filled p-orbital or pi-system, stabilizing carbocations and alkenes. It's often called “no-bond resonance.”

Looking at situations where multiple possible elimination products are possible, and labeling them as Zaitsev or Hofmann based on relative degrees of substitution.
