The 1-H NMR spectrum of a compound of molecular formula C3H6Cl2 shows only two multiplets, a triplet at 3.72 ppm and a quintet at 2.23ppm. The high-field:low-field integration ration is 2:1. Deduce the structure of the organic hald and explain the NMR signals. I'm thinking it's 1,1-dichloropropane.
How many grams of magnesium chloride must be dissolved in 568 g of water to give a solution that freezes at -2.38°C
Explain why the elimination reaction in acetone promotes an E2 mechanism while water promotes and E1 mechanism? Which product is more thermodynamically stable, the E or Z isomer?
Calculate the number of moles of solute present in eahc other following solutions: a) 60.0g of an aqueous solution that is 1.25 percent KI by mass, b) 250g of an aqueous solution that is 0.460 percent NaCl by mass, c) 0.600L of 1.25M H2SO4.
You have 1005.3 g of a bleach solution. The percent by mass of the solute sodium hypochlorite, NaOCl, is 3.62%. How many grams of solvent are in the solution?
To resolve an object in an electron microscope, the wavelength of the electrons must be close to the diameter of the object. What kinetic energy must the electrons have in order to resolve a protein molecule
What pressure will the sample have if the volume changes to 268 mL while the temperature is increased to 815 K?
although even more strained than cyclopro-panone, is nevertheless quite stable and can even be distilled. Explain, taking the polarity of the carbonyl group into account.
The compound Mg(OH)2 is basic, but Si(OH)4 is an acid (silicic acid). Why? Select all that apply. 1. The OH groups attached to the silicon atom in Si(OH)4 strengthen the OH bond so that a hydrogen ion dissociates when the compound is dissolved in ..
Sodium bicarbonate is called baking soda because when heated, it releases carbon dioxide gas, which is responsible for the rising of cookies, doughnuts, and bread. Calculate the volume (in liters) of carbon dioxide by heating 4.37 g of sodium bica..
