WebOct 1, 2024 · When in reactive mode, you can turn trivial things into full-blown crises. While your friend’s, partner’s, child’s, and boss’s behaviors are all out of your control, your own … Induction is the redistribution of electron density through a traditional sigma bonded structure according to the electronegativity of the atoms involved. The inductive effect drops across every sigma bond involved limiting its effect to only a few bonds. Conjugation is a redistribution of electron density similar to induction but transmitted through interconnected pi-bonds. Conjugation is not only affected by electronegativity of the connected …
