`CH_(3)COO^(-)` (acetate ion) is more stable than `C_(2)H_(5)O^(-)` (ethoxide ion). Explain.

Text Solution

Verified by Experts

The correct Answer is:
`(##ALN_CHM_C09(II)_E01_775_A01##)` `CH_(3)-CH_(2)-O^(-)`
Electron delocalion, as shown by following resonance strucutres, causes the negative charge in acetate to be shared equally by both oxygens. This type of resonance effect is not possible in ethoxide ion
`(##ALN_CHM_C09(II)_E01_775_A02##)`
