    Side Chain Oxidation

    Hello I had a few questions if anyone could help me out. I wanted to convert toluene into benzoic acid via side chain oxidation using potassium permanganate. However, I'm a little unsure of the mechanism. If I'm right, you convert toluene into benzyl alcohol using NaOH, and then from...

    Polarity Question

    This is a pretty basic polarity question but I'm having a hard time deciding. I had to choose the two major products of methylbenzene with HNO3 and H2SO4. I said that the two major products were O-methylnitrobenzene (1-methyl-2-nitrobenzene) and the other 1-methyl-4-nitrobenzene...

    A problem relating to density and layers

    Hi, I recently had a lab where I had to separate a mixture of benzoic acid and benzil. So, I dissolved the mixture in ch2cl2 and then added NaOH in order to convert the benzoic acid into its sodium salt. At anyrate, this then produced the aqueous and organic layers. However, I noticed that...

    Need help with conduction and oscillation question.

    Hi, these two questions have been boggling me for a week.. if anyone can I help I'd be very appreciative. The first one is.. A cylindrical rod of length 1.5 m and radius 0.02 m is insulated to prevent heat loss through its curved surface. One end is attached to a thermal reservoir at 573...

    Adiabatic Expansion - Need help getting started

    Hi, I just need help getting started on a question.. I'm not even sure where to begin: It is desired to ignite a gas at 1000 degrees celcius by compressing it adiabatically to 27 degrees celcius. a) by what ratio must its volume be changed? I'm not really sure how to approach this...

    A question about elevators

    Hi, there's a question in the book that says: "An elevator of height 3 m moves upward at 2m/s. A ball is dropped from the roof. a) when does it hit the floor? b) what is the total distance travelled relative to the ground?" Now, the way I had set it up was that when the ball drops, it falls...

    Cheetah Physics Question Help

    The question is: A cheetah cah hit 105 km/h in 2s, and maintain this speed for 15 s, while an antelope can reach 90km/h in 2s and sustain this for a long time.. if they are both separated by 100m and the antelope reacts 0.5s after the cheetah starts running, will they meet? and if not, when...

    Some physics help needed

    Hi, I'm having a bit of trouble with a problem.. basically the question is as follows: A particle falling covers 64% of the entire height in its last second of the fall. What is the total height of the fall? I've tried equating two formulas, and a few other things but I can't seem to go...
