Question

C-1 : never break a single bond while drawing a resonance structure.

C-2 : never exceed the octet of a second-period atom (C, N, O).

For the curved-arrow move described below, which statement is correct ?

structure

The C=C pi electrons are pushed to make a new C=C bond with the carbonyl carbon, while the C=O bond is left as it is.

TestHub · Accepted Answer

The carbonyl carbon would carry a double bond to O and a new double bond to carbon, five bonds in all. C-2 is violated.
