Question

what type of intermolecular forces is/are present in tecl4?
london dispersion forces only
dipole - dipole forces only
london dispersion forces and dipole - dipole forces
dipole - dipole and hydrogen bonding
dipole - dipole, hydrogen bonding, and london dispersion forces
ionic
ionic and london dispersion forces

Explanation:

1. First, note that TeCl4 is a covalent - molecular compound. It has no ionic bonds as it is formed by non - metals (tellurium and chlorine).
2. Analyze the molecular geometry: TeCl4 has a see - saw molecular geometry due to the presence of a lone pair on the central tellurium atom. The bond dipoles do not cancel out completely, so the molecule is polar, which means dipole - dipole forces are present.
3. All molecules, regardless of polarity, exhibit London dispersion forces due to temporary fluctuations in electron density.
4. Hydrogen bonding is not present because there is no hydrogen atom bonded to a highly electronegative atom (N, O, or F) in TeCl4.

Answer:

C. London Dispersion forces and dipole - dipole forces
