WebApr 27, 2012 · Furthermore, since they possess O-H or N-H bonds, they can also participate in hydrogen bonding. These solvents can also serve as acids (sources of protons) and weak nucleophiles (forming bonds with strong electrophiles). They are most commonly used as the solvent for their conjugate bases.
Webthe alkyl group and the halide (fluoride, chloride, bromide, or iodide) are designated as separate words-The alkyl group is named on the basis of its longest continuous chain beginning at the carbon to which the halogen is attached.-Functional class names are part of the IUPAC system; they are not "common names." WebThis hydrogen bonding lowers the escaping tendency of both molecules and as a result, the vapour pressure of the solution is less than that expected from Raoult’s law. On the other hand, in the pure state, only the weak forces of Van der Waal hold both chloroform and acetone molecules.
