Chemistry Questions

Do you not have the spectralchemical and trans effect list/line/whatever in front of you? Did you just start inorganic?

Actually, I haven´t had a single organic chemistry class in my whole life. They have given us this test so that we must research online to find out about how to solve these questions.

Oh I see, then I am much more sympathetic.
For this, I am pretty sure Wikipedia has both the spectrochemical and trans effect series, and probably an explanation but basically, if a ligand (term used to describe the element or compounds attached to the central metal atom) appears further on the right side of the spectrochemical series, it is a stronger ligand, and according to most literature I have found, a stronger ligand replaces a weaker one. However, according to my professor, who while young is a recognized inorganic researcher, only the trans effect really matters when determining ligand substitution. The trans series is organized in a similar way, and the farther to the right the ligands are, the more likely that the ligand opposite (or trans) will be substituted. That explanation was probably confusing so sorry, but shouldn't be that tough to find an easier explanation. The slightly confusing thing though, is that for parts b and d, in chemical reactions we assume that a variety of isomers are usually formed, but most are either re-reacted into the preferred isomer or just made in such small qualities that we say the reaction only has one product, even when in step 2 there could technically be other product formed. Only when noticeable percentages of product formed is of another isomer, like in some organic reactions, do we consider it, if you understand what I mean.

Thanks for your support. Some of the questions in this test are in a chemistry university level. So I will try to discuss with my own teacher about what you said.

Now, here's the next question:

(a) false, iodine is a weak field ligand (weaker than chloride anyway)

>https://en.wikipedia.org/wiki/Ligand#Examples_of_common_ligands_.28by_field_strength.29

(b)true, the molecule is planar (and the example on
>https://en.wikipedia.org/wiki/Trans_effect#Kinetic_trans_effect
covers a similar transformation, except I(-) is even more trans effect than Cl(-) and NH3)

(c)true, the AgI is dumped out and pulls the equilibrium forwards

(d)false, once the intermediate is formed (with only one Cl- ligand) the trans effect takes over and forms the product

I can't believe that only 2 years after getting my Masters in Chemistry that I've forgotten literally everything. Also that I just fucking Google everything even though there is a load of textbooks 3 feet away.

Well, I guess I will have to give the rest of the questions to you guys tomorrow. Seems like I have an another test online tonight and I'll be studying for it for the rest of today. Thank you all for helping me for now. See you guys tomorrow morning

Anons? Are you out there?

I think I need to hand back my degree, this is giving me a headache.
