You see how you said chlorine has 6 valence electrons and aluminium has 4 valence electrons should the chlorine not be negative because it has more electrons. If not why is that? It's at 1:15
@ProfessorDaveExplains9 жыл бұрын
Random Help In the catalytic complex, chlorine will have a formal positive charge because it's showing 6 electrons in the lewis dot structure, one per bond and two lone pairs, compared to its typical valence of 7. One fewer electrons means a positive charge. Aluminum shows 4 electrons, one per bond. Its typical valence is 3 so this has a formal negative charge.

it's because friedel-crafts alkylation involves the formation of a carbocation on the alkyl fragment as an intermediate in the mechanism, and carbocations are highly unlikely to form on sp2 carbons.
