Aug 3, 2016 at 18:35 comment added nvja @S.Chevalier Chelintsev's model could not deny resonance per se, because its measurable effects were undeniable. But he was uncomfortable with the thought that electrons move from place to place without a pulling /pushing measurable force. The absence of a force jarred with materialism - the basis of "Marxist science". So he called the effects "mutual influences", to make them seem force-y. I think. In my understanding, re-wording is also the way to obsolescence for +E, -E. Chelintsev was at the forefront for <6 years and failed to muzzle critics. "Marxist chemistry" is stretching it.

Aug 3, 2016 at 15:17 comment added SteffX Sorry my comment was a bit misleading. I am not saying it was a convention but I have seen arrows from a proton to a double bond (and it actually makes sense in the context of electromeric effects). Maybe it was just a bad scheme.
Aug 3, 2016 at 14:54 comment added SCH Are you sure @SteffX? This page shows curved arrows "symbolizing the displacement of electron pairs". I'm genuinely curious.
Aug 3, 2016 at 14:11 comment added SteffX In the schemes describing electromeric effect, some arrows describe the movement of chemical species but standards now use arrows to describe the movement of a pair of electrons. The electromeric effect (on a scheme) is then implied.
