In addition, to find which compound has more basic strength, basicity, would you also have to compare conjugate acids? *That is, discovering the conjugate acid of the basic compound, ranking those on acidity, and then reversing the order ranked to find the most/least basic?

What is the critical importance of edta? *I have been hearing this term a lot recently, and I was wondering if someone could explain the composition of edta, and the properties it has

While I understand that the coordination number denotes the number of ligands attached to a central atom, what importance does this serve to discover any further aspects of the molecule involved?

In conjunction with hybridization, I am confused as to why we denote elements molecules with notation such as sp^2, on the basis of its lone pair & type of bond it shares? What does this notation serve to inform viewers of, other than clutter up a Lewis drawing with more information?

So, in relation to sigma and pie bonds, does each increase in bond length constrain the molecule on an increasing number of axis(s)? That is, a sigma bond just constrains it on an axis, a pi bond would not allow it to rotate, and a triple bond would mean even more constraints in molecular movement?

Also, just to be clear, when asked to name the VSEPR shape of a molecule, that would not be the same as asking to name the molecular shape of a molecule? *This would revolve around not counting in the lone pairs for the molecular shape. Also, which one of these two are we most likely to be asked to ...

In the construction of Lewis models, is the rule for expanded octets as follows: If it is on period (3) of the periodic table or lower, it will be able to handle an expanded octet? *Does this follow for all elements on period (3) of the periodic table?

Additionally, part of the question was a comparison of two double bonds, each with two lone pairs. In this scenario, how would you discover which of the two bond lengths was longer? * Also, is it correct in thinking the lone pairs stretch out the bond length?

Anthony Mercado 1K

If every double bond is one sigma and one pie bond, why not simply denote double bonds as such since the beginning? Or is this statement not reversible, in which a sigma and pie bond together do not always make a double bond?

In reference to the construction of double/triple bonds in Lewis structures, will it be acceptable to make quadruple bonds within compounds? *I believe Dr. Lavelle briefly talked about this during lecture

In the scenario of two elements being isoelectronic, why wouldn't the element gaining or losing electrons entirely become the other element it's isoelectronic to? Ie. Why wouldn't F- just become Ne?

Why do we even classify compounds with bonds lengths and strengths? I was led to believe that these are never a true depiction of such, in relation to concepts such as the average bond length of resonance structures

Anthony Mercado 1K

Would it ever be possible for an element with a radical electron, in a compound, to have a formal charge of zero? As well, is there a lowest amount of elements in a compound where it is unnecessary to calculate formal charge?

Anthony Mercado 1K

Would it also be applicable to just state the average length, in Angstrom units, of the bond lengths, in a scenario of possibly interchangeable single and double bonds? * Or would this poorly depict the image of resonance structures?

Anthony Mercado 1K

How is it that radical structures even appear? I would assume that the octet rule is the final test for determining if a compound is really able to exist. That being said, is it that radical electrons appear solely in nature or are they man-made?

Why is there no energy level after the f block? By having energy levels end at the f block, what is this representative of?

Anthony Mercado 1K

What is the reasoning behind, for one to remember, no electrons being found in the radial node in correlation with it having no density?

Anthony Mercado 1K

Do the lobes of an orbital dictate the exact location of where an electron may appear, or the general area of where it can be found?

Anthony Mercado 1K

Would a typical question ask one to find both the frequency and the wavelength, and if so, what order would they need to found in?

Anthony Mercado 1K

Are photons comparative to electrons in some sense, and could we think of them similar to atoms in some ways?

Anthony Mercado 1K

Are there any cases as to which a wave would be acting neither constructively or destructively, in some other alternate format?

Anthony Mercado 1K

That being said, will utilizing 15.99 grams/mole or 16 grams/mole entail that the TA(s) or test grader understands the differences in sig figs the end answer will hold because of these varying numbers/computations?

Anthony Mercado 1K

If the molar masses for both the empirical and molecular formula are the same, does this conclude with being able to find the molecular formula from the start of the problem, bypassing calculations for the empirical formula?

Anthony Mercado 1K

Additionally, and this may be overcomplicating matters, how would one expect to organize elements if they are made up of two letters, such as Cr - Chromium, or if one element, out of the ones in the compound has the largest number of atoms?

Anthony Mercado 1K

In a typical "finding the molecular formula problem," is there a way to discover the molecular formula before the empirical formula, in order to save critical time during an examination?

Anthony Mercado 1K

So, in terms of the molecular and empirical formulas being the same, when no simplification can be done, how can we be aware of this occurring in a problem (ie. knowing beforehand if they'll be the same or not) without a diagram?

Anthony Mercado 1K

As an inquiry into discovering the molecular formula of didemnin-A, in the primary steps towards conversion would one have to convert mg units to g towards the end or beginning of calculations? * Would these affect the number of sig figs due to constant conversions?
