Document Summary
Lipid organic molecule of biological origin that is insoluble in water and soluble in nonpolar solvents (e. g. ch3cl2) Noncovalent force attractive force (other than covalent bonding) between atoms or molecules. Boiling point temp at which vapor pressure of substance = ambient pressure. Chemical bond sharing (even or uneven) of electron pair. Covalent bond approx equal sharing of electron pair. Ionic bond highly unequal sharing of electron pair. Reaction mechanism step-by-step description of bond changes. Nucleophile a reactant that provides a pair of electrons to form a new covalent bond. Electrophile a reactant that accepts a pair of electrons to form a new covalent bond. pka a quantitative measure of acidity. (it measures how far to the right the proton transfer equilibrium lies. The more negative the pka, the greater the extent of ionization, the stronger the acid) Inductive effect transfer of charge (electron withdrawal or donation) through a chain of atoms in a molecule by electrostatic induction.
