Do we need to rethink inductive effects in organic chemistry?
6+ day, 1+ hour ago (563+ words) Every first-year organic chemistry student learns early on about the inductive effect, which describes how certain atoms" electronegativity can affect other atoms in the same molecule. This subtle electronic push and pull, they are told, extends through several nearby bonds…...
