Nucleophile - CORRECT ANSWER-An electron pair donor; includes H2O, CN, F, X
Electrophile - CORRECT ANSWER-An electron pair acceptor; includes H, AlCl3, X-X
Polar Covalent Bond - CORRECT ANSWER-A covalent bond between atoms that differ in
electronegativity. The shared electrons are pulled closer to the more electronegative atom,
making it slightly negative and the other atom slightly positive.
Non-Polar Covalent Bond - CORRECT ANSWER-a covalent bond in which the bonding electrons
are shared equally by the bonded atoms, resulting in a balanced distribution of electrical charge
CH3 - CORRECT ANSWER-methyl
CH2CH3 - CORRECT ANSWER-ethyl
,CH2CH2CH3 - CORRECT ANSWER-propyl
OCH3 - CORRECT ANSWER-methoxy
OCH2CH3 - CORRECT ANSWER-ethoxy
OCH2CH2CH3 - CORRECT ANSWER-propoxy
NH2 - CORRECT ANSWER-amino
H-bonding - CORRECT ANSWER-IMF; involves carboxylic acid, alcohol, esters; has the presence
of ether or halogen; must include N-H.
Dipole-Dipole Interactions - CORRECT ANSWER-IMF; involves ketones, aldehydes, esters; has the
presence of ether or halogen.
London Dispersion Forces - CORRECT ANSWER-IMF; only IMF that occur between hydrocarbons;
involve instantaneous dipoles.
Substitution Reaction - CORRECT ANSWER-Reaction involving the exchange of one group for
something different; keeps the same number of electron bonds.
Elimination Reaction - CORRECT ANSWER-Reaction involving the loss of bonds within a
molecule; results in less bonds within product.
Addition Reaction - CORRECT ANSWER-Reaction involving adding a bond to a molecule that
wasn't there; results in more bonds in product -- usually on adjacent carbons; identified by a
double bond in reactant.

write 568.762 in scientific notation - CORRECT ANSWER-5.68762 X 10^2
write .00000772 in scientific notation - CORRECT ANSWER-7.72 X 10^-6
in scientific notation if the decimal point is move to the right is the exponent on 10 negative or
positive? - CORRECT ANSWER-negative
in scientific notation decimal points move to the left have a negative or positive exponent on 10?
- CORRECT ANSWER-positive
in scientific notation if decimal are not move what is the exponent on 10? - CORRECT ANSWER-0
what is the unit for area? - CORRECT ANSWER-m^2
what are the units for speed? - CORRECT ANSWER-m/s meters per second
what are the units for force? - CORRECT ANSWER-kg m/s^2 = Newton (N)
what are the units for pressure? - CORRECT ANSWER-kg/ m*s^2 or Pascal (pa)
what are the units for energy? - CORRECT ANSWER-(kg*m^2)/s^2 or joule (J)
1dm^3 equals how many L - CORRECT ANSWER-1
