    Chemistry How Can Isoxazole Be Synthesized from Furoxan and Phenylacetylene?

    I'm having difficulties uploading my work to this system at the moment, but I have currently attempted 1,3-cycloaddition between the furoxan and phenylacetylene. However, unless a sigmatropic rearrangement occurs (which, as far as I can conclude, leads to instability with charges), this places...

    Does Tautomerization Regenerate Phenylethanone in NaH Reaction?

    The instructions only specified that phenylethanone would react with NaH followed by an acid quench. I know that NaH provides a hydride (H-), and this will "take" one of the hydrogens on the exposed methyl group. I followed this by pushing electrons so that the negative charge was on the...

    Organic Chemistry: Alkenes and Diazomethane

    I'm having difficulties figuring out where the new carbon-carbon bond would form. Any help is greatly appreciated. Thank you!

    Why Am I Struggling with This Nucleophilic Reaction Problem?

    Oh. Sorry. It was an Sn1 on the non-bridgehead!

    Why Am I Struggling with This Nucleophilic Reaction Problem?

    I got it! Thank you so much for helping me reason through it!

    Why Am I Struggling with This Nucleophilic Reaction Problem?

    I guess, geometrically, it doesn't look like it will be able to attack either from the backside. So it would be an SN1, then? Also, I thought there could be no reaction at the bridgehead because it cannot be planar, or it is too unstable. Is this correct?

    Why Am I Struggling with This Nucleophilic Reaction Problem?

    Would SN2 be more likely? I tried a substitution at the top bromine atom with the nucleophile -CN, but it was incorrect. I'm not sure where to go from there. For SN1, the carbocation at the top would be disubstituted. I'm assuming that the bromine at the bridgehead doesn't participate in any...

    Why Am I Struggling with This Nucleophilic Reaction Problem?

    I have attempted this problem several times, but I keep on getting an incorrect answer. I have tried mostly substitution reactions (SN1 and SN2) on the top bromine atom, and I know that a double bond cannot be formed at the bridgehead. Any help in the right direction is greatly appreciated. Thanks!

    Salt Bridges in Cells: Voltage & Distance

    Thanks for all the help! I think I have a solid answer, now.

    Salt Bridges in Cells: Voltage & Distance

    I know that salt bridges maintain charge, thus allowing the reaction to proceed. I was wondering if the distance of the electrodes from the salt bridge affects the voltage of the cell in any way. Thanks!

    Finding Components of Velocity on a Ramp

    Thank you so much! I guess the wording of the problem and my teacher's strictness with regards to the axis threw me off, initially, but now I understand. Thanks, again!

    Finding Components of Velocity on a Ramp

    So I would need to use Newton's Laws? I will try using that knowledge, as well. Also, can I state that a=gsinθ along the ramp if the axis for this problem is not to be set along the ramp? Thank you for your time.

    Does a Sliding Mass on an Incline Have a Horizontal Acceleration Component?

    1. For the following, the x-axis is not allowed to be set along the ramp. If a mass, starting from rest, slides along a linear, frictionless incline of length D and then falls a distance h to the ground, will it have an x-component of acceleration? 2. Relevant kinematics formulas? 3. I...

    Finding Components of Velocity on a Ramp

    Thanks. I'll give that a shot.

    Finding Components of Velocity on a Ramp

    I hadn't even thought of that. Do you happen to know how to make sense of this problem using solely kinematics equations? Does the rock have x and y components of acceleration?
