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 $C H_{3} C H_{2} COC H_{3}$ the $C = O$ pi electrons are pushed onto oxygen and the electrons of a C-H bond of the $C H_{2}$ group are pushed to make a $C = C$ bond with the carbonyl carbon.

The first arrow is allowed. The second arrow breaks a C-H single bond. C-1 is violated.
