What effects does change in structure and as a result biodistribution have on a drug? (Physico-Chemical Properties of Drugs) Changes the solubility, metabolism, and excretion properties of the drug within the limits of the biological target. Electrolytes Ionic/ weak acid or base Hydrogen Bonds Hydrogen bonds form between polar groups Interaction between an electronegative atom (O, N, S) and a polarized hydrogen. Polarized H is one that is bound to an electronega...

EAS: friedel-crafts alkylation correct answers -the friedel-crafts alkylation makes it possible for us to install an alkyl group onto an aromatic ting -this is accomplished by reacting an alkyl halide with a lewis acid to generate a species that is electrophilic enough to react with benzene -good at forming carbon-carbon bonds EAS: Friedel-Crafts alkylation-reagents correct answers -alkyl halides are generally electrophilic but no electrophilic enough to attract the benzene ring -it was fo...

Organohalides - ANSWER-Organic molecules contain Halogen atoms. Ex. Algae, Mollusk, sponges, can be industrially used - solvents, insecticides, herbicides, cleaning fluids, fire retardants, refrigerants. Can also be used as inhaled anesthetic. More important in organic chemistry because of theur reactivity. Two of the most important reaction types typical of organic Halides are.... - ANSWER-Substitution Elimination Substitution Reaction - ANSWER-Replacing the halogen in a molecule with a...
