structure Give the structure that corresponds to the following molecular formula and NMR spectra: C6H14O 1H NMR: ? 0.91 (6H, d, J = 7 Hz); ? 1.17 (6H, s); ? 1.48 (1H, s; disappears after D2O shake); ? 1.65 (1H, septet, J = 7 Hz). 13C NMR: ? 17.6, ? 26.5, ? 38.7, ? 73.2.

Freezing Point Depression

Freezing Point Depression

Freezing Point Depression When a pure solvent freezes the temperature remains constant till all liquid is frozen (thus the freezing point). When the solvent in a solution freezes the temperature keeps decreasing. Explain why you do not see a steady freezing point for a solution.

1H NMR spectrum

1H NMR spectrum Give the structure that corresponds to the following molecular formula and 1H NMR spectrum: C7H12Cl2: δ 1.07 (integral = 6203, s); δ 2.28 (integral = 1402, d, J = 6 Hz); δ 5.77 (integral = 700, t, J = 6 Hz). Note: The integrals are given in arbitrary units.

Haber Process

Haber Process

Haber Process Consider the reaction that occurs during the Haber process: N2(g) + 3H2 (g) –> 2NH3 (g). The equilibrium constant is 3.9×10^5 at 300 K and 1.2×10^-1 at 500 K. Calculate delta h reaction and delta s reaction. I calculated delta H reaction to be -93 kJ and thats correct but I’m not sure […]
