    Where Should I Zero the NMR Spectra of Dimethylacetamide in CDCl3?

    We used 3% TMA?

    VSEPR t-shaped geometry vs trig. planar

    This is a really good question that I can't answer but I hope someone can. Maybe it has to do with hybridization? By trigonal planar I'm assuming you mean that the molecule has trigonal bipyramidal geometry but places the lone pairs at 180 from each other?

    Where Should I Zero the NMR Spectra of Dimethylacetamide in CDCl3?

    Homework Statement I have a spectra of the NMR, I'm just confused on where to `zero' the spectra at? Homework Equations The Attempt at a Solution There are two peaks around zero in the spectra (one is bigger than the other but not by much). Also the two peaks are much much smaller than the...

    [P CHem] HCL/DCL r and p branch J value assignment

    Homework Statement Assign J values for P and R branches of H35cl, H37cl, d35cl, and d37cl compounds. Homework Equations The Attempt at a Solution I have a fundamental IR spectra I did on and HCL/DCL compound. I'm extremely confused how to assign J values. I've been looking online...

    [Statistics] measuring values against known value

    Nevermind y'all, was a silly mistake. I can easily do a one sample t test

    [Statistics] measuring values against known value

    Homework Statement You use a standard gram weight of known weight (x) to check the accuracy of a balance. For one balance, this standard is weighed 3 times yielding the following values; a, b, and c. Calculate the 95% confidence limit for the mean Homework Equations general statistics...

    Ligands and lowering reduction potential

    Hi I have a question I was wondering if y'all could clear up. Let's say I have two metal cations, Iron (III) and Manganese (II). Will binding them to an anionic ligand lower their reduction potentials (making each a better redundant) and if so why? Is it because the anionic charge of the...
