Rank each of the following compounds in decreasing order of reactivity towards Friedel-Crafts alkylation. Most reactive = 1; if a compound will not react, rank it as "non" rather than assigning a numerical value.
Compound A: benzoic acid
Compound B: benzaldehyde
Compound C: iodobenzene
Compound D: benzenesulfonic acid
Hydrogen and iodine gases react to form hydrogen iodide gas. H2(g) + I2(g) → 2 HI(g) At a certain temperature and pressure 0.70 L of H2 reacts with 0.70 L of I2.
What mass of precipitate will form if 1.50 L of concentrated Pb(ClO3)2 is mixed with 0.850 L of 0.190 M NaI? Assume the reaction goes to completion.
Write down the secular determinant for the allyl radical, Ch2=CH-Ch2, and estimate the pi-binding energy.
The mass of the ice cube is 11.2 g, and its initial temperature is -12.8 °C. The water resulting from the melted ice reaches the temperature of your skin
Describe why this is based on the wavelength range that is transmitted. What color would you see if you mixed the two solutions with ?max = 520 and ?max = 610?
For the reaction 2HI(g) H2(g) + I2(g), Kc = 0.290 at 400 K. If the initial concentrations of HI, H2, and I2 are all 1.50 × 10-3 M at 400 K, which one of the following statements is correct
