Cyclopentadiene Diels-Alder Reaction with itself Cyclopentadiene is unstable because it rapidly undergoes a Diels-Alder reaction with itself. Carefully draw the structure of the product, showing stereochemistry clearly. (Recall the “endo rule” for Diels-Alder reactions.)
105 mL of H2O is initially at room temperature (22.0 degrees celcius). A chilled steel rod at I am running a midnight deadline so if anyone coming across this can answer, I’d be grateful! (i) 105 mL of H2O is initially at room temperature (22.0 degrees celcius). A chilled steel rod at 2.0 degrees celcius […]
Titration – Volhard method chloride in a brine solution is determined by the Volhard method. A 10.00 mL aliquot of the solution is treated with 15.00 mL of standard 0.1182 M AgNO3 solution. The excess is titrated with standard 0.101 M KSCN solution, requiring 2.38 mL to reach the red Fe(SCN)2+ endpoint. Calculate the conce…
Equilibrium Consider the reaction below for which K = 74.0 atm-1. A(g) + B(g) ? C(g) Assume that 0.314 mol C(g) is placed in the cylinder represented below. The barometric pressure on the piston (which is assumed to be massless and frictionless) is constant at 1.00 atm. The original volume (before the 0.314 mol […]
This is a chemistry problem dealing with equilibrium constants The question is Consider the following reaction and its equilibrium constant 4CuO(s) + CH4 (g) = CO2 (g) + 4 CU (s) + 2 H2O (g) Kc = 1.10 A reaction mixture contains 0.22 M CH4, 0.67 M CO2 and 1.3 M H2O. Which direction will […]
