Problem: Consider the reaction shown below. (a) Draw all four carbocation intermediates possible from protonation of the diene. Don't forget to include any resonance structures! (b) Identify the most stable carbocation intermediate and explain why it is the most stable. (c) Draw the arrows for the first step of the mechanism to show the formation of the most stable carbocation intermediate. (d) Draw the alcohol product(s) formed by attack of water on the most stable carbocation intermediate. (e) Draw the arrows to show how one alcohol product is formed from the carbocation. Include intermediates, as needed. (f) Which of the alcohol products would you expect to be formed in the greatest amount at low temperatures? Explain. (g) Which of the alcohol products would you expect to be formed in the greatest amount at high temperatures? Explain. $H_2SO_4$ ? $H_2O$
Justice Holmes made all of the following arguments in his Buck v. Bell decision except: Group of answer choices Carrie Buck failed to challenge her unjust confinement in Virginia when she had the chance Carrie Buck had been granted due process of law in Virginia through a sterilization hearing that was fair and proper since courts have granted government the power to mandate vaccines, it follows that government must have the power to force citizens to be sterilized if the government has the power to force citizens to fight and die as soldiers, then it clearly has the power to stop “idiots” from sapping the power of the nation

Convert the point $(\rho, \theta, \phi) = \left(1, \frac{2\pi}{3}, \pi\right)$ to Cartesian coordinates. Give answers either as expressions, or decimals to at least one decimal place. $(x, y, z) = $
Find all \(x\) such that the distance between the points \((2, -6)\) and \((x, -5)\) is 17. \(x = \) Note: If there is more that one \(x\), give a comma separated list (i.e.: 1,2).
Texts: Use Chebyshev's inequality to answer: a. Is there any random variable X for which is satisfied: P [μX - 2σX ≤ X ≤ μX + 2σX] = 0.6, where μX is the expected value of X and σX is the standard deviation of X? b. If X is a random variable such that E[X] = 3 and E[X^2] = 13, determine a lower bound for P[-2 < X < 8].
