Free-radical halogenation can occur with chlorine and a source of direct UV radiation or sunlight. Chlorination via radical halogenation is a very unselective process and can lead to the formation of all three of the below products. Estimate the relative percentages of each product that will be formed using this means of halogenation. Presume that 1 equiv. of chlorine is used.
What is the velocity of an electron that has a de Brogile wavelength of 4.22 nm?
A general statement concerning the solubility of organic compounds is: The smaller molecules dissolve best in a solvent with a low molecular weight.
