chemical bonding and molecular geometry pt. 2

Question 1

multiple bonds

Answer 1

are bulkier than single bonds so they behave like lone pairs and alter bond angles

Question 2

VSPER

Answer 2

valence shell electron-pair repulsion; structure around atom determined by minimizing electron pair repulsion

Question 3

dipole moment

Answer 3

property of a molecule whose charge distribution can be repreented by a center of positive charge and a center of negative charge

Question 4

what an electronegativity arrow is pointing to

Answer 4

is the negative charge center

Question 5

where an electronegativity arrows tail is located

Answer 5

is the positive charge center

Question 6

there is no net dipole moment/ a molecule is nonpolar when

Answer 6

identical polar bonds (arrows) point in opposite directions

Question 7

there is a net dipole moment/molecules are polar when

Answer 7

identical polar bonds do not point in opposite directions/face each other

Question 8

steric number

Answer 8

number of atoms connected to the central atom

Question 9

ligands

Answer 9

number of bonds/lines to central atom

Question 10

lone pairs

Answer 10

the number of two remaining electrons around an atom that fill its electron shell

Question 11

electron geometry

Question 12

molecular shape

Question 13

bond angle
