Thank you very much, DrClaude. Could you tell me why hydrogen more readily/commonly bonds to the nitrogen? Thank you very much for your time and help here

I can't figure out why hydrogen is more likely to bond to either the nitrogen or to the sulphur atom. I can't locate any information in any textbooks or online as to which molecule is more prevalent/common. This is not a homework question. I just came across one of these molecules and wondered...

Yes! Thank you

I have no idea. What do you think?

Because nitrogen is more electronegative, the resonance structure on the left will predominate

ahhhh, reasoning from my two previous responses, I suppose because nitrogen is more electronegative, and because it carries the negative charge on the deprotonated form (thiocyanate) then it is most likely to form a bond with the hydrogen atom

It is only one form, but it would be the most common form as it has the lowest formal charge (a single negative charge) and the negative charge is on the most electronegative atom.

Sorry, I was confusing there. Nitrogen is more electronegative than is sulphur which implies that when involved in a chemical bond, nitrogen will draw (relatively) more electron density towards itself than would sulphur. But because both tautomer forms will produce molecules with formal charges...

Well the formal charges are the same, so I don't believe they will contribute. My next thought is that electronegativity may contribute, but for the same reason as formal charge, I don't believe that should matter either. I then wondered about tautomerization and have spent some time on Google...

Oh I see I worded it backwards (which makes it even more confusing). My resource only shows thiocyanic acid as an option--I was actually just trying to discover for myself if isothiocyanic acid can or does exist. Could you help me understand why the H-N form of the tautomer is more common than...

Hello and thank you very much for your response, Could you also help me understand why the hydrogen is 20x more likely to bond with the sulphur than with the nitrogen? Cheers

I'm aware that the structure on the left is correct, but given that the formal charges are the same for each structure, I can't figure out why hydrogen is more likely to bond to the sulphur atom than it is to the nitrogen atom. Thank you for your help here!

How do I determine which group is dash (into the page) and which is wedge (out of page)? Won't that literally change which isomer it is? How to determine optical activity then? (I believe that in order for something to be optically active it has to be an enantiomer--a non-superimposable mirror...

Thank you That is what I thought, but I wanted a professional opinion. Have a great day

Provided solution in the textbook. That's how they justify the force being positive while maintaining the torque as negative. NB. I just realized that by cutting and pasting, the -90 showed up as 290 for some reason. I corrected it in my above comment, but it may not be showing in your...
