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 ?
In cyclohexene the electrons of a C-C single bond are pushed to make a new pi bond.

The arrow starts at a sigma (single) bond, so a single bond is broken. C-1 is violated.
