pleas help:

and can you please cite from where did you get the information.

Study the following ylide. used in the reaction. Is the circled ester group electron donating or electron withdrawing? Relative to the partially negative carbon nucleophile, is the ester group stabilizing the partial negative charge or destabilizing the partial negative charge? Study the following ylide. Is the circled methyl group electron donating or electron withdrawing? Relative to the partially negative carbon nucleophile of the ylide, is the methyl group stabilizing or destabilizing? In the proper solvent systems, which (A or B) would you expect to react faster?

Explanation / Answer

HW4 : Electron withdrawing

HW5: stabilizing the partial negative charge

HW6 : Electron donating group

HW7:  detabilizing

HW8: ylide A because it is more stable
