(1) Predict the structure of (x) and (Y) in the following sequence : (1) Excess MeMgBr →(X)-> (Y) → (2) Et20 10 fü p-methylphenol on reaction with OH/CHCl3 gives two products. Write the structure of both and propose a suitable mechanism. 10
show the mechanism using arrows and formal charges and lone pairs. Step 1 HCI (cat.) MeOH Whome OMe OH Bry > Br? YN OBn dBn5 OBn
6. For the following reaction, + H20* + Cl - > OH + 2H2O Show the mechanism.
(6) Show that the semicircle C = {(x,y) = R2 | + y2 = 1, y > 0} is a 1-dimensional manifold with boundary and the hemisphere D= {(x, y, z) | 22 + y2 + z2 = 1, 2 > 0} is a 2-dimensional manifold with boundary. (7) Suppose X is an n-dimensional manifold with boundary. Let ax denote the set of points in the boundary of X. Show that ax is an (n-1)-dimensional manifold.
Question 9 Consider the following mechanism: 1. Clo (aq) + H20(1) <=> HClo(aq) + OH (aq) FAST 2. 1(aq) + HClO(aq) => HIO(aq) + Cl (aq) SLOW 3. OH"(aq) + HIO(aq) => H2O(l) + 10 (aq) FAST What is the role of HIO? Selected Answer: C. reactant Correct Answer: D. intermediate
Find the probability that Y is greater than 3. Let Y have the probability density function f(y) = 2/y3 if y> 1, f(y) = 0 elsewhere.
(10pts) 3. Use direct proof to show that if x and y are positive real numbers, then (x+y)" > " + y".
