The greatest resonance contributor to the resonance hybrid has to be determined from the following resonance structures. Concept Introduction: The unshared electrons of an atom that does not involve in bonding are called lone pair. Curved arrows are necessary in drawing the resonance structure. Curved arrows has a head indicating that the electrons are coming and tail indicating that the electrons are going. The two rules in drawing the resonance structure is, Breaking of single bond is not allowed. Never exceed an octet for second row elements. When a single Lewis structure does not represent a structure adequately, the true structure is the intermediate between the two or more structure referred to as resonance structure. Most stable structure contributes most to the resonance hybrid.

I have a question about this problem involving mechanisms and drawing curved arrows for acids and bases. I know we need to identify the nucleophile and electrophile, but are there different types of reactions? For instance, what about Grignard reagents and other types that I might not be familiar with? Can you help me with this? I want to identify the names of the mechanisms for problems 1-14, such as Gilman reagents and others. Are they all the same? Also, could you rewrite it so I can better understand? The handwriting is pretty cluttered. Additionally, I need to label the nucleophile and electrophile, but my main concern is whether those reactions differ, like the "Brønsted-Lowry acid-base mechanism, Lewis acid-base mechanism, acid-catalyzed mechanisms, acid-catalyzed reactions, base-catalyzed reactions, nucleophilic substitution mechanisms (SN1 and SN2), elimination reactions (E1 and E2), organometallic mechanisms, and so forth."
