• / 3

⩥ halides are classified. Answer: F, Cl, Br, I and classified based on the

carbon bonded to the halide (1*,2*,3* or aryl)

⩥ Amines are classified by the number of. Answer: carbons bonded to the

nitrogen (1*,2*,3*,4*)

⩥ aryl halide. Answer: a halocarbon in which one or more halogens are

attached to the carbon atoms of an arene ring

⩥ ion-ion interactions. Answer: attractive forces between two charged

molecules and are the strongest

⩥ hydrogen bonding. Answer: the intermolecular force in which a

hydrogen atom that is bonded to a highly electronegative atom is attracted to an unshared pair of electrons of an electronegative atom in a nearby molecule H to O,N

⩥ dipole-dipole interactions. Answer: attractive forces that act between

polar molecules C-O, N, Cl, F

⩥ ion-dipole forces. Answer: attractive forces between an ion and a polar

molecule

⩥ London dispersion forces. Answer: The intermolecular attractions

resulting from the constant motion of electrons and the creation of instantaneous dipoles -increase in strength as contact surface increases -greater contact surface area means more effective LD int. and higher BP 2 / 3

⩥ more electrons. Answer: more polarizable or how easily the electron

cloud can be distorted and higher melting/boiling point

⩥ Pauli Exclusion Principle. Answer: no more then two electrons can occupy a

single orbital; two electrons in the same orbital must have opposite spins

⩥ Aufbau Principle. Answer: each successive electron must fill the lowest

energy orbital available

⩥ Hund's Rule. Answer: before a second electron can be paired in the same

orbital, all other orbits at the same energy must contain a single electron

⩥ valence electrons. Answer: occupy the highest energy

ex: carbon is the n=2 shell

⩥ core electrons. Answer: occupy the remaining lower energy shells of the

atom

ex: carbon occupy n=1 shell

⩥ # of valence electrons. Answer: group #

⩥ As bond strength increases, bond length _______.. Answer: decreases

⩥ covalent bond. Answer: two or more nonmetal atoms toward share

electrons
