Which of the two structures (A) and (B) given below is more stabilised by resonance. Explain (A) CH_(3)COOH (B) CH_(3)COO^(-) |
|
Answer» Solution :(B) `CH_(3)COO^(-)` is more stabilised (A) Resonance structure of `CH_(3)COOH`:  The separation of charge is in structure (II) so, it is more ENERGY containing and less stable. `THEREFORE` There is a less stabilisation of structure (A). (B) Resonance structure of `CH_(3)COO^(-)`:  Both the resonance structure of compound (B). i.e. x and y are of eqal energy and hence contribute equally towards the resonance hybrid of structure (B) is more stable than structure (A). |
