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

In cyclohexene the C=C pi electrons are pushed to the neighbouring ring CH₂ carbon to make a new double bond with it.

The neighbouring sp³ carbon already has four bonds. A new double bond gives it five. C-2 is violated.
