Problem- i. Comment on the stereoselectivity of the bromination of E-stilbene (assign stereochemistry of dibromo product, why selective?, is this molecule chiral?)
Comment on the regioselectivity of the bromination of acetanilide (assign regiochemistry of bromo product - ortho/meta/para, why selective?)
Why do we use alternative brominating agents in this experiment?
I am need of complete solution for this problem please help- me out to get right solution
Calculate the equilibrium concentrations for all species: B. Calculate the value of the equilibrium constant, K.
Charcoal is primarily carbon. Determine the mass of CO2 produced by burning enough carbon to produce 5.00 x 102 kJ of heat. C(s) + O2(g) = CO2(g) DH = -393.5 kJ

Which class of materials, biological organisms, biological chemicals, or non-biological chemicals react most dramaticallyto the addition of acid or base. How does this relate to their complexity
12.0 moles of gas are in a 3.00L tank at 22.7C. Calculate the difference in pressure between methane and an ideal gas under these conditions. The van der Waals constants for methane are a=2.300L^2*atm/mol^2 and b=0.0430 L/mol.
Problem- Suppose a solution contains 0.28 M Pb2 and 0.46 M Al3 . Calculate the pH range that would allow Al(OH)3 to precipitate but not Pb(OH)2. The Ksp values for Al(OH)3 = 4.6×10-33 and Pb(OH)2 = 1.43×10-20
