(3) what is your prediction for the next reaction? B) I think it is best to analyze this t-state as 3 fragments defined by the breaking and forming bonds (as done above, like the Diels-Alder reaction) instead of arbitrarily establishing a strong relationship between the carbon fragments and then using this to interact with the hydrogen 1s (as 5-electron organic fragment).
