Ethyl acetate example:
Predictions:
Position | Integration | Splitting | Chemical Shift |
---|---|---|---|
1 | 2 | Three nearest neighbours that are equivalent – quartet | Single bond to oxygen – deshielded |
2 | 3 | Two nearest neighbours that are equivalent – triplet | Saturated alkyl group far from ester group – shielded |
2′ | 3 | No nearest neighbours – singlet | Adjacent to the carbon of a carbonyl – slightly deshielded |
