Do weak intermolecular forces have high viscosity?
a) The weaker the intermolecular forces in a liquid, the higher the viscosity. b) The stronger the intermolecular forces in a liquid, the lower the viscosity.
Is viscosity a result of intermolecular force?
Viscosity increases as intermolecular interactions or molecular size increases.
What type of forces are responsible for viscosity in liquids?
Cohesive forces between like molecules are responsible for a liquid’s viscosity (resistance to flow) and surface tension (elasticity of a liquid surface).
What intermolecular force has the highest viscosity?
hydrogen bonds
Viscosity is governed by the strength of intermolecular forces and especially by the shapes of the molecules of a liquid. Liquids whose molecules are polar or can form hydrogen bonds are usually more viscous than similar nonpolar substances.
What is one reason why intermolecular forces are weaker than intramolecular forces?
Intramolecular forces are stronger than intermolecular forces, because the attractions that hold compounds together are stronger than the attractions between molecules.
Why intermolecular forces are weaker than bonding forces?
Because it is the power of attraction or repulsion between atoms or molecules instead of sharing or giving/taking electrons. This slight polarity will make the molecule itself slightly negative at one point and slightly positive at another.
What factors affect intermolecular forces?
Intermolecular forces are essentially due to electric field interactions. Accordingly, the two major factors are polarisation and polarisability. Polarisation is essentially the dipole moments in the molecule.
How can I identify intermolecular forces?
To determine the intermolecular forces of a molecule or chemical, you must first construct the electron dot structure (Lewis structure). Then you determine the polarity of the molecule. Once you have those done determining the types of intermolecular bonds become much more simple.
What are the properties of intermolecular forces?
The Effects of Intermolecular Forces on Material Properties. Intermolecular forces and the bonds they produce can affect how a material behaves. In the case of water, the relatively strong hydrogen bonds hold the water together. Two of the resulting properties are high surface tension and a high heat of vaporization.
What is a weak intermolecular force?
Intermolecular forces are weak relative to intramolecular forces – the forces which hold a molecule together. For example, the covalent bond, involving sharing electron pairs between atoms, is much stronger than the forces present between neighboring molecules.
