I don't know if I have the same book as the topic starter (Organic Chemistry 7th edition by L.G. Wade Jr) but my book also mentions the E2 reaction occurring when there's a syn-coplanar relationship between the leaving group and an H when there is no free rotation (like in a cycloalkane). The...

One the practice problems i was doing in preparation for my exam was to rank the following nucleophiles in the order of decreasing reactivity, best nucleophile first. Nucleophiles: CH3OH, Br-, NH3, F-, CH3S- The answer was CH3S->Br->NH3>F->CH3OH What I don't understand is why CH3S- is...

Thanks, that cleared things up for me.

Your net Fx is incorrect, it should be Nsin(theta)=mv^2/R not -Nsin(theta)=mv^2/R

Homework Statement Piston 1 in the figure below has a diameter of 0.31 in.; Piston 2 has a diameter of 1.7 in. In the absence of friction, determine the force vector F necessary to support the 500 lb weight. Homework Equations F1/A1=F2/A2 The Attempt at a Solution I used...

For some reason, the program does not give me the correct answer probably because the course administrator has turned that function off. I'll send my answer to my professor and see what he says.

Hmm, the online homework thing rejected my answer. Since I used up all my tries I can't submit any more answers. I hope I'm not missing anything in my answer.

Homework Statement The polymerization of propene to polypropylene progresses through a radical mechanism. Complete the propagation step of the reaction mechanism diagram by drawing in the missing lone pairs, radical electrons, atomic charges, and electron-flow arrows where appropriate. 2...

You're basically given two position functions that describe where the particle is at a given time and you have to find the velocity and acceleration of the particle given the position functions. Knowing that velocity is a derivative of position and that acceleration is a derivative of velocity...

Thanks for your input, I'll be sure to ask my professor about this problem.

Homework Statement A high diver of mass 50.0 kg jumps off a board 10.0 m above the water. If her downward motion is stopped 2.30 s after she enters the water, what average force did the water exert on her? Homework Equations Fnet=ma vf2=v02+2ax The Attempt at a Solution First...

Homework Statement A student decides to move a box of books into her dormitory room by pulling on a rope attached to the box. She pulls with a force of 80.0 N at an angle of 21.0° above the horizontal. The box has a mass of 25.0 kg, and the coefficient of kinetic friction between box and floor...

Ok, so I used your way and did P=nk which means that P/n = k, so P1/n1=P2/n2=k. After substitution that gives me 7.4/n1=3.6/n2. I then found the ratio of n1 to n2 to be n1/n2= 7.4/3.6 = 37/18 so I interpreted that to mean that we started out with 37 mols of C2H2 initially and ended up with a...

ok, so so far i have 3C2H2-->C6H6 ntotal=nC2H2 final + nC6H6 \frac{P_{C_{2}H_{2 initial}}}{n_{C_{2}H_{2 initial}}}=\frac{P_{C_{2}H_{2 final}}}{n_{C_{2}H_{2 final}}} from avogadro's law PC2H2 final=Ptotal-PC6H6 nC6H6=nC2H2 final-ntotal=nC2H2 final-(PtotalnC2H2 final)/PC2H2 final nC2H2...

ok, thanks i'll try to work it out from there, also, am i on the right track with 3C2H2-->C6H6 or is this chemical equation irrelevant to solving the problem?
