alpha.chem.umb.eduIntermolecular Forces • List the substances BaCl 2, H 2, CO, HF, and Ne in order of increasing boiling points. • The attractive forces are stronger for ionic substances than for molecular ones • The intermolecular forces of the remaining substances depend on molecular weight, polarity, and hydrogen bonding. The

secure-media.collegeboard.orgonly possible intermolecular forces are London dispersion forces. The London dispersion forces are stronger in I because it is larger in size with more electrons and/or a more polarizable electron cloud. The stronger London dispersion forces in I result in a higher melting point,which makes I 2 a solid at room temperature.

The forces holding the solute together must be broken (requires energy) Ionic compounds – the forces holding the ions together must be broken Covalent molecules – the forces holding molecules together must be broken 2. The intermolecular forces (between particles) holding the solvent together must be broken (requires energy) 3.

www.nios.ac.inmolecules which are held together by intermolecular forces. At room temperature, these atoms/molecules have finite thermal energy. If thermal energy increases, molecules begin to move more freely. This state of matter is said to be the gaseous state. In this state, intermolecular forces are very weak and very small compared to their kinetic energy.

ncerthelp.comViscous forces are intermolecular forces acting between the molecules of different layers of liquid moving with different velocities. where, (dv/dx) = rate of change of velocity with distance called velocity gradient, A = area of cross-section and = coefficient of viscosity. SI unit of η is Nsm-2 or pascal-second or decapoise.

www.acs.orgintermolecular forces. So when sugar dissolves in water, the attractive forces between the individual molecules are overcome, and these molecules are released into solution. Food-coloring molecules are usually ionic solids, that is, they contain positive and negative ions, which are held together by ionic bonds.
