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 $C H_{3} C H_{2} - N H_{2}$ the lone pair on nitrogen is pushed to make a $C = N$ bond with the $C H_{2}$ carbon.

The C H 2 ​ carbon already has four bonds. A new C = N bond gives it five. C-2 is violated.
