Web9. nov 2024 · 1 It may be meant as a -I effect, compared to an ethene hydrogen formally replaced by the phenyl. Similarly as methyl has +I effect on benzene, formally replacing a benzene hydrogen. By everyday life analogy, if 2 persons stand on the same stair, one of them is higher than the person that originally stood 1 stair lower. – Poutnik WebThe mesomeric effect (M) produces, as a result of an interaction through the π-electrons, an electron excess or deficiency depending on the nature of the substituents. If a substituent having double bond or nonbonding electrons is directly attached to a conjugated system, the electron density and consequently the chemical shift will change. ...
