This is useful for one of the steps of the mechanism.2. Since both molecules have possible nucleophilic and electrophilic sites, use trial and error to see what happens. Follow the instructions below, and analyze whether the product is reasonable or not. i) Note: In order to not overfill an octet, pi electrons need to become a lone pair. We've practiced this with resonance, now you're going to practice it with chemical reactions. Nuc O NH₂ Elec directly attach to S. Do not overfill octets This product is unreasonable because:
