From the table of available reagents, select the one(s) you would use to convert toluene (shown below) to each of the following products. Reagents available a. H2CrO4 e. CO2 b. Br2, Δ f. H3O+ c. NaOH g. ethylene oxide d. Mg, Et₂O h. PCC (Use the minimum number of steps; in no case are more than six steps necessary. List reagents by letter in the order that they are used (example: fa). If an acid workup is required, for example after a Grignard reaction, it must be specified.) (a) (b) OH

Okay, can someone please explain in vivid detail the rules of alkene reactions? We are covering 1-Hydrohalogenation, 2-Acid-catalyzed hydration, 3-Hydroboration oxidation, 4-Hydrogenation, 5-Halogenation, 6-Halohydrin, 7-Epoxidation, 8-Ozonolysis. For these reactions, when is it Markovnikov vs. anti-Markovnikov? When is it syn addition or anti-addition? When does it form 2 products vs. 1? And what is '50/50'? Any help is greatly appreciated.

3. The figure shows the cross-section of a hollow cylinder of inner radius a = 3.00 cm and outer radius b = 6.00 cm, and an edge view of a rectangular loop with sides $d_1$ = 3.0 cm and $d_2$ = 10.0 cm and total resistance of 0.35 ?. A uniform current density $J = J_0e^{-at}$ flows through the cylinder in direction parallel to its axis coming out of the page, where $J_0 = 8.00 \times 10^5$ A/m$^2$. At time t = 20.0 ms, the magnetic flux through the rectangular loop is $7.88 \times 10^{-5}$ Wb. Find the magnetic field as a function of time at distance 5.00 cm away from the axis of the cylinder. (You can ignore the induced current in the loop)
