Why does NCl3 have a similar boiling point to C2H5OH?
Its a 4 marker plz helpp

But you will get the marks for discussing the relative effect of each tpe of intermolecular force in the two molecules.
For example:
Nitrogen trichloride: London dispersion forces and dipole-dipole interaction. The LDF are strong because of the (relatively) high relative mass of the molecule (120.5). Dipole dipole interactions are weak.
Ethanol: London dispersion forces, dipole dipole interactions and hydrogen bonding. The LDF are much weaker as Mr = 46, but the hydrogen bonding increases the boiling point. Dipole dipole interactions are weak.
