I think its the one with the lowest energy and ive been hearing that we also have to draw all the resonance structures but I remember Lavelle saying that he would take any structure.

I asked my homie if he wanted to go to a party on Halloween and he said "Sodium Bromine Oxygen" :((((( because he had chem 14 A lecture on the next day.
its essentially H-N-C-C-O-H with an hydrogen connected to the 1st carbon on the lewis structure and on the second carbon a double bond forms with oxygen. the first nitrogen also has a single bond with a hydrogen.

in the book it says, "the total Coulomb potential energy V(r) is the sum of the individual coulombic attractions and repulsions." Hope this helps.
for a, its an ionic compound not a molecular as expected because there exists exceptions to the nonmetal-metal ionic compound. So it essentially would be the same N in the middle with H surrounding it and a - outside to show its power. then the Cl next to it with the electrons showing. for a, its a...
Although ionic compounds usually occur between metals and nonmetals, there are a few exceptions, such as ammonium chloride, which is an ionic compound. Its expected to it to be molecular because it contains only nonmetals. But it contains the NH4+ (ammonium) ion, combined with a chloride ion. Hope t...

I think its more based on electronegativity. Coordinate covalent bonds between two main group elements are more polar and sensitive to phase changes than normal covalent bonds. Sorry, hope this helps!

Yes, it essentially follows the radii trend on the periodic table, so up the rows and to the right on the columns polarizing power decreases. Hope this helps!
Im not sure what problem you are referring to because 2b. 23 asks to "Determine the formal charge on each atom in the following molecules. Identify the structure of lower energy in each pair."
I remember Dr. Lavelle saying something about if the problem had resonance structures, then we could draw which ever structure we wanted and it would count. I would draw the most stable one though and show that there are more resonance structures. Hope this helps!
