How does one electronegative atom change the electron density several bonds away? See sigma-bond polarisation pass along a carbon chain and fade with distance.
You will learn:
how chlorine polarises a sigma bond and the next bond along the chain
why the inductive effect weakens with distance
what +I and −I mean, and why they are relative to a reference
how alkyl donation can stabilise a carbocation but disfavour a carbanion
when resonance, hybridisation, sterics or the solvent can change the order
Includes a worked question (chlorine at C-2 vs C-4 of butanoic acid) and a pause-and-predict practice question.
