Homework Answers
- AIBN also known as azo-bis-isobutyronitrile is toxic and unstable (it produces nitrogen gas and radicals upon heating. This means it is potentially explosive. Rest assured, the reagent will be measured for you in a vial in very small quantity. But, if you have any exposure, let your instructor know and rinse the exposed area for fifteen minutes with cold water.

2 Another possible product of the E1 dehydration of 2-methylcyclohexanol is methylenecyclohexane (see structure below), but it is formed only in trace amounts Draw the reaction mechanism, including curved arrows as appropriate, for the formation of this product. Why is this product minor, rather than major?

Hi could you help me with this problem: A stick AB with its center of mass at G, length 2b. Initially, the stick stands horizontally on the ground, without any initial velocity. Slightly push the stick , it starts to fell. Assume that A slides without friction on the ground, find the velocity of G when the stick touches the ground. Thank you very much!

pleas help 5,6,7,8,9,10
III IV 5. The product of free-radical halogenation reactions is an alkyl halide. The major amount of this halide forms during the second step of propagation. However, you should be aware that one possible termination step also forms alkyl halides. Why does the majority of the alkyl halide product come from the propagation step and not the termination step? A. At any given time during the reaction, the concentration of both the alkyl radical and the halide...
I was wondering if you could help me better understand this Statistic problem about a spinner?...
I was wondering if you could help me better understand this Statistic problem about a spinner? I feel as though I am not setting the problem up right. Would I use binomial distribution? Here is the problem: A spinner is spun 16 times. (picture a spinner with four parts numbered 1, 2, 3 & 4) (a) What is the probability of spinning fewer than four three's? (b) What is the mean of the distribution? (c) what is the standard deviation?...
