is?​

Answer 1

Answer:

Two Important Reaction Patterns: Ortho- , Para- Directors and Meta- Directors

It’s one thing to learn about electrophilic aromatic substitution reactions of benzene itself. But once you move beyond benzene, that’s when things start getting really interesting.

Today we’ll describe the two main patterns by which substituents “direct” electrophilic aromatic substitution. In one pattern, substituents direct the reaction to give either the “ortho” (1,2) or “para” product, with a slight preference for “para” (1,4). In the second pattern, a different family of substituents direct the reaction to give primarily the “meta” (1,3) product.
