0:03
walls forces are weak intermolecular
0:05
forces that arise between molecules or
0:07
atoms due to Temporary or permanent
0:10
dipoles they play a crucial role in

molecular interactions and properties

types of vendor walls forces these
0:17
forces include London dispersion forces
0:20
dipole dipole interactions and hydrogen
0:23
bonding each type differs in strength
0:25
and arises from various molecular
0:27
characteristics London dispersion forces
0:31
these are temporary forces resulting
0:32
from fluctuating electron distributions
0:35
in atoms or molecules they are present
0:38
in all substances even non-polar
0:40
molecules like noble gases dipole dipole
0:44
interactions these occur between
0:46
molecules with permanent dipoles where
0:48
the positive end of one molecule
0:50
attracts the negative end of another
0:52
water molecules exhibit strong dipole
0:55
dipole interactions hydrogen bonding a
0:58
special case hydrogen bonding is a
1:01
strong form of dipole dipole interaction
1:03
occurring when hydrogen is bonded to
1:05
highly electronegative atoms like oxygen

impact on molecular attraction Vander
1:17
walls forces dictate how molecules
1:19
interact influencing boiling and melting
1:22

1:25
example stronger forces result in higher
1:28
boiling points roll in biological
1:30
systems in biology these forces
1:33
stabilize protein structures DNA based
1:36
pairing and cell membrane interactions
1:38
crucial for maintaining life

processes applications in nanotechnology
1:43
vaner walls forces are significant in
1:46
nanotechnology where weak molecular
1:48
attractions affect the behavior of
1:50
materials like carbon nanot tubes and
1:52
graphine limitations and characteristics
1:55
while relatively weak compared to
1:57
chemical bonds V der wal's forces are
2:00
cumulative in large systems their
2:02
Collective impact can be
2:05
substantial why they
