What are intermolecular forces?
Attractive forces that exist between molecules
View source
How do intermolecular forces compare to covalent bonds?
Intermolecular
forces
are
much
weaker
than
covalent
bonds
View source
What are the three main types of intermolecular forces?
Induced dipole-dipole forces (
London dispersion forces
)
Permanent dipole-dipole forces
Hydrogen bonding
View source
In what order are the three types of intermolecular forces listed based on their strength?
Induced dipole-dipole forces
,
Permanent dipole-dipole forces
,
Hydrogen bonding
View source
What is the strength of induced dipole-dipole forces?
Weak
View source
Where are induced dipole-dipole forces found?
In all molecules and
noble gases
View source
What causes induced dipole-dipole forces to arise?
Temporary fluctuations in the
electron distribution
around atoms
View source
How do larger atoms and molecules affect induced dipole-dipole forces?
Larger atoms and molecules have stronger induced dipole-dipole forces due to more
electrons
View source
How does surface area influence induced dipole-dipole forces?
Molecules
with larger surface areas have stronger induced dipole-dipole forces
View source
What trend is observed in the boiling points of group 4 hydrides?
Boiling points increase
down the group
View source
What is the relationship between molecular size and boiling points in group 4 hydrides?
Larger molecular size leads to more electrons
Increased
electron density
creates stronger
induced dipole-dipole forces
Resulting in higher boiling points
View source
What holds molecules together in a molecular lattice structure?
Induced dipole-dipole forces
View source
Why do noble gases condense into liquid and solid states at low temperatures?
Weak
induced dipole-dipole forces
allow them to condense
View source
What causes permanent dipole-dipole forces in polar molecules?
Unequal sharing of electrons in
covalent bonds
View source
How do permanent dipole-dipole forces arise?
Electrostatic attractions between the
partial positive
and negative ends of
polar molecules
View source
In hydrogen chloride (HCl), what causes the polar nature of the bond?
The greater
electronegativity
of
chlorine
compared
to hydrogen
View source
How do polar molecules experience both permanent and induced dipole-dipole forces?
They have
permanent dipoles
and also experience induced dipole-dipole forces
View source
Why does methanal (CH2O) have a higher boiling point than ethane (C2H6)?
Methanal has stronger
intermolecular forces
due to its
polarity
View source
What is the strongest type of intermolecular force?
Hydrogen bonding
View source
What are the requirements for hydrogen bonding to occur?
Hydrogen must be bonded to
F
,
O
, or
N
, and there must be a
lone pair
on the adjacent atom
View source
How do hydrogen bonds form between molecules?
Attraction between the
positively charged
hydrogen and the
negatively charged
lone pair on
F, O, or N
View source
What are the effects of hydrogen bonding on the properties of substances?
Greater
solubility
in water
Higher
melting
and
boiling
points compared to similar-sized molecules without hydrogen bonding
View source
Why does water (H2O) have a higher boiling point than other group 6 hydrides?
Water can form
hydrogen bonds
, requiring more energy to overcome
View source
How does hydrogen bonding affect the density of ice compared to water?
Ice is less dense than water due to the arrangement of molecules in a
lattice structure
View source
What is the impact of intermolecular forces on the melting and boiling points of substances?
Stronger
intermolecular forces lead to
higher
melting and boiling points
View source
How do intermolecular forces influence the solubility of substances in water?
Polar molecules that can
hydrogen bond
are soluble
Non-
polar molecules
with only
induced dipole-dipole forces
are typically insoluble
View source
Do covalent compounds conduct electricity?
No
, covalent compounds
do not
conduct electricity
View source
Why do polar molecules not conduct electricity?
They are
electrically neutral
overall and do not carry
charge
