Document Summary
The bond strength of c-x decreases as the size of x increases. Electrophilic carbon is subject to attack by nucleophiles. Cations and other electron deficient species attack the halogen. Haloalkanes have higher boiling points than the corresponding alkanes. London forces arise from mutual correlation of electrons among molecules. Strongest when the outer electrons are not held very tightly around the nucleus. Polarizability is the degree to which an atom or group"s electron cloud is deformed under the influence of an external electric field. The more polarizable the group, the stronger the london interactions, the higher the boiling point. The reagent attacks the haloalkane and replaces the halide. Substrate is the organic starting material that is the target of attack by a nucleophile. 6. 3 reaction mechanisms involving polar functional groups: using electron-pushing arrows. Curved arrows depict the movement of electrons textbook notes page 1.
