1.8 - 1.11

Question 1

bonds between atoms with very large electronegativity differences (about _________) are usually drawn as ionic

Answer 1

1.5-2

Question 2

resonance structures

Answer 2

structures where 2+ valence-bound are possible able, differing only in placement of electrons

Question 3

resonance hybrid

Answer 3

actual molecule is hybrid of resonance forms

Question 4

delocalized molecule

Answer 4

positive/negative charge is spread out over molecule/atoms

Question 5

resonance-stabilized cation

Answer 5

spreading the + charge over 2 atoms to make the ion more stable than if the entire charge where localized on certain atoms

Question 6

resonance: move _________ not ____________

Answer 6

electrons, atoms

Question 7

do ind. resonance forms exist

Answer 7

no, forms hybrid w/ characteristics of both

Question 8

major contributor

Answer 8

more stable resonance structure, closer representation of real molecule, has lowest energy

Question 9

molecular formula

Answer 9

number of atoms of each element in one molecule of the compound

Question 10

empirical formula

Answer 10

relative ratios of the elements present
