The electron region geometries will be ___ (the same/different) as the molecular
geometries when there are no lone pairs of electrons around the central atom,
but they will be ___ (the same/different) when there are lone pairs present on the
central atom. - answer the same
different
List the order of sizes from largest to smallest, regarding lone pairs and bonds. -
answer lone pair > triple bond > double bond > single bond
Lone pairs occupy ___ (more/less) space than single bonds. - answer more
Double bonds occupy ___ (more/less) space than triple bonds. - answer less
The force between an ion and a polar molecule is called ___. - answer ion-dipole
The force between two polar molecules is called ___. - answer dipole-dipole
, The force between a polar molecular and a non-polar molecule is called ___. -
answer ion-induced dipole
The force between any two molecules that each have at least one electron is
called ___. - answer London dispersion force
Larger and heavier atoms and molecules exhibit ___ (stronger/weaker) dispersion
forces than those found in smaller and lighter atoms and molecules. - answer
stronger
A molecule that has a charge cloud that is easily distorted is said to be ___ (not
very/very) polarizable and will have large dispersion forces; one with a charge
cloud that is difficult to distort is ___ (not very/very) polarizable and will have
small dispersion forces. - answer very
not very
A molecule that has a charge cloud that is easily distorted is said to be very
polarizable and will have ___ (small/large) dispersion forces; one with a charge
cloud that is difficult to distort is not very polarizable and will have ___
(small/large) dispersion forces. - answer large
small
How does surface area influence dispersion forces? - answer Greater surface area
increases contact availability for other molecules, which results in stronger
