Definition of electron-withdrawing neighbours
Check what you remember
Read the wording for your board, then hide it and explain electron-withdrawing neighbours in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
An oxygen, a halogen, a carbonyl group or a benzene ring pulls electron density away, leaving the nucleus less shielded so it resonates further left at a higher delta value.
