VSEPR 3 Flashcards
HCL means
Hydrogen chloride
Dipole moment of molecule indicated by
Arrow with a cross at one end
Verticals bar at left end shows the atoms that is
Donating the electron
Because no arrowhead is in opposite direction, HCL is considered to be a _ molecule
Polar
Arrow also points to more _ atom
Electronegative
Arrow pointing to more electronegative atom indicates where
Electrons are most likely to be found
Diatomic molecules have no difference in
Electronegativity
_ are Nonpolar
Diatomic molecules
Atoms don’t need to be _ for bind to be labeled nonpolar
The same
Carbon’s electronegativity is
2.5
Hydrogen electronegativity is
2.1
2.5 - 2.1 =
0.4
Nonpolar covalent bonds form between atoms with an electronegativity difference between _ and _
0
0.4
Polar covalent bonds form between atoms with electronegativity difference of (range)
0.5
1.7
Molecular polarity depends on the _ and how the electron pairs occupy space
Shape of the molecule
Molecular polarity depends on the shape of the molecule and
How the electron pairs occupy space
Bonds are polar if they have an electronegativity difference greater than
0.5
The entire molecule is polar if shape is
Asymmetric
To represent 3d, Lewis dot uses _ to represent atom farther away in a bond
Dotted line
SNAP acronym
