hard 6 marker electronegativity questions

Use the concept of electronegativity to justify why the acid strengths of ethanedioic acid and ethanoic acid are different.

Stage 1:

-acids are of the form RCOOH but in ethanol acid R= CH3

Stage 2

-the unionised COOH group contains two very electronegative atoms therefore has a negative inductive effect

Stage 3

-The O-H bond in the ethanedioc acid is more polarised so more dissociation into H+. Ethandioic acid is stronger than ethanoicacid
