We have to find the compound C .
Why the product I formed is wrong and how is the correct product is formed .

I would start by drawing the correct lewis structure for the alpha beta unsaturated ester.

Also as a general rule you should not expect a bond to silver in the major organic product of a reaction. Ag+ is much more likely to be essentially a spectator, or perhaps a lewis acid in the mechanism. Overall you can probably safely ignore it, except for the fact that it tells you fluorine is an anion.

in the following reaction we have to find the major product .

according to me it will be C compound beacuse of anion (intermediate) stability.

Among the following compounds I think D compound has more rate of solvolysis in 50% aq.ethanol at 45°C than compound C .
Due to more resonance.
But the compound C has more rate . Why?
