    Reaction of thiols with vinyl ethers

    The interaction between oxygen in vinyl ether and hydrogen in thiol activates the double bond. The beta carbon has a partial positive charge and attracts sulfur. Then the bond between sulfur and hydrogen is broken. The alpha carbon then abstracts the proton from oxygen, giving the...

    Calculating Force Constant for a Harmonic Oscillator: Units and Conversions

    Hmm, one more question. The final answer I get is in units of kg/s2. It's true that, when the distances are canceled in the final unit requested in the problem, that these units are correct. How do I apply these distances to the number? For instance, let's say I got 1 kg/s2. Can I just multiply...

    Calculating Force Constant for a Harmonic Oscillator: Units and Conversions

    So, in other words, your suggestion is multiplying wavenumbers by the speed of light, which will result in a normal frequency (s-1). Even if this is done, I end up with mass/s2 which is... force/distance I guess, which is correct. Ok, cool. Thanks.

    Calculating Force Constant for a Harmonic Oscillator: Units and Conversions

    I know but the problem is the units of this problem itself. I need the units to be in energy/distance^2 which is proper but the output of the equation includes mass and energy (amu and wavenumbers^2) which, from what I can tell, can't be converted to any form of a force constant, which is why...

    Calculating Force Constant for a Harmonic Oscillator: Units and Conversions

    Sorry, I meant force/distance. My question still stands.

    Identifying β-Naphthol Using Dye Test: Acidic, Neutral, and Alkaline Solutions

    Think about the mechanism for phenyl ring activation. How will a positively charged diazo compound react with a nucleophillic phenyl ring?

    Calculating Force Constant for a Harmonic Oscillator: Units and Conversions

    Homework Statement A molecule is a harmonic oscillator, and has a fundamental frequency of 1000 cm−1 and a reduced mass of 10.0 amu. From this, determine the magnitude of the force constant, and express it in units of aJ ˚A−2 (atto joules per angstrom). Homework Equations ω=√(k/mr) The...

    Energy Probability of Electron in 1d box

    Looking back on this two weeks later, what you were saying makes sense. I guess I just hadn't made connections between the math and concepts at that point. Thanks for your help.

    Energy Probability of Electron in 1d box

    I ended up using a Fourier expansion to solve for each wavefunction coefficient. Is this what you were hinting at?

    Energy Probability of Electron in 1d box

    Homework Statement We're given an unnormalized state function ψ(x) of an electron in a 1 dimensional box of length pi. The state function is a polynomial. We're asked to find the probability that a measurement of its energy would find it in the lowest possible energy state. Homework Equations...

    What Are the Products of Benzonitrile with CH3CH2CH2Cl and CH3COCl Using AlCl3?

    You're correct for the first one, although I was taught that Friedel-Crafts alkylations are unreactive to deactivated benzenes, as well as poorly reactive to an alkyl chain longer than 2 carbons. For the second one, Friedel-Crafts acylations are nonreactive to deactivated benzenes.

    How can you find this differential equation?

    I'm not actually sure what I'm looking for. I asked my professor what form he wanted our answer in and he said he can't tell me, I suppose it gives the answer away. From my understanding, a differential equation is one where the left hand side is the derivative of a variable that is on the...

    How can you find this differential equation?

    My question is about a differential equation, not about the derivative of the function. I just gave the information to aid in answering my question over the differential equation, since I don't know where to start.

    Which Type of Bond is Strongest in Chemistry?

    It tends to be a matter of difficulty deciding whether ionic or covalent bonds are stronger among the chemistry community. Generally, people who think ionic bonds are stronger point to melting point decomposition. Table salt, for example, has a very high melting point and decomposition...

    How can you find this differential equation?

    No, the lowercase and uppercase are the same. Merely a typo. Wouldn't there be a natural logarithm in the answer? \frac{d}{dn_{A}} \frac{RT ln(\frac{n_{A}}{n_{T}})}{\frac{n_{A}}{n_{T}}} = RTn_{T} \frac{d}{dn_{A}}\frac{ln(\frac{n_{A}}{n_{T}})}{n_{A}} = RTn_{T}...
