intermolecular forces Flashcards
Why the shape of a molecule is important?
The shape of a molecule may determine its properties and uses
what are The 5 Main VSEPR Shapes and their angles
linear- 180 trigonal planer - 120 tetrahedral - 109.5 trigonal bipyramid - 90 and 120 octahedral - 90
how can you tell if its a bonding domain in a Lewis dot diagram?
by the solid lines
how many domains have to be present to form a linear domain geometrically?
2
how many domains have to be percent to form a trigonal planer domain geometrically?
3
how many domains have to be present to form a tetrahedral domain geometrically?
4
what are Bonds in the plane of the paper are shown as?
lines
what are Bonds projecting in front of the plane of the paper are shown as?
triangles
what are Bonds projecting behind the plane of the paper are shown as?
stacked lines
is there Symmetry of Larger Molecules for polarity?
yes
what are The 5 Main VSEPR Shapes and state if they are polar or not
Linear molecules Nonpolar if the ends are the same Polar if the ends are different Tetrahedral Nonpolar if all 4 corners are the same Polar if even 1 corner is different Trigonal Pyramids Always polar
dont need
dont need
if the polarity is symmetrical is there any polarity?
no
what are Intermolecular forces?
the attraction between positive and negative polarities
what determines the strength of the intermolecular force?
The electronegative difference of two elements bonded together
