36) determine the kinds of intermolecular forces that are present in each element or compound. a. k b. ncl3 c. sih4 d. hf

I think the intermolecular forces would be,
Kr - London dispersion forces, It is intermolecular forces present in molecules and atoms. Kr is a noble gas in which atoms are joined by dispersion forces.
NCl3- Has both dispersion forces and dipole-dipole forces. Dipole-dipole is a type of intermolecular forces present in polar molecules.
SiH4 - It is a non polar molecule therefore it has london dispersion force as the intermolecular force.
HF-  It is a polar molecule and has dipole-dipole force. Hydrogen bond also exists between F and H
