I have a freshman requirement as a science student for at least 3 core science classes, and I picked physics as often as I could. However, I must choose either chem or bio as my third. I chose bio.
The thing is, I'm deathly afraid of chemicals. I don't know when it started, but I can hardly touc...
@hBy2Py the problem was the gaussian output of mass weighted normal coordinates vs the non-mass-weighted ones in the formula that I used to create the dimensionless displacements
@pH13-YetanotherPhilipp Ahhh, yep, that'll do it. ORCA is kind enough to try to tell you what it has output, but I found the message very cryptic until I'd researched the calculation method enough to understand what it was talking about.
The above compound is said to be hydrolised more easily than this under Alkaline medium . How is this possible ?
I thought due to resonance NO2 acquires negative charge which faces repulsion from the solvation effect by basic medium. But it will be relatively easier for oxygen in ch3o( in 2nd...
The answer states that since the rate determining step is attack of water on carbonyl group, so the hydration of nitro group is not significant here
But since resonance is a continuous process, so the actual thing to exist will be the resonance hybrid.
So I mean, what I want to say is, that resonance will be happening before and even during the addition of water to carbonyl group, and so a partial negative charge will still exist on the nitro group, which will somewhat repel water.
So, in short, I think that what we have to explain here that inspire of a negative charge on the nitro group in one of the canonical structures, why does the hydrolysis take place at the first compound. Is my interpretation correct?

I am confused as to why the presence of a negative charge on nitro group was not considered in the rate determining step. Am I missing something here?
@Mithoron Yes, so that is why I am having a conceptual doubt. What is the actual picture? Is solvation simultaneous here in the resonance hybrid, or what?
Ok.. And was I correct in saying that in the resonance hybrid, a partial negative charge will be present on the nitro group, even in the rate determining step?
