Based on the following information:
CF4, Molecular Weight 87.99, Normal Boiling Point -182°C
CCl4, Molecular Weight 153.8, Normal Boiling Point -123°C
The intermolecular forces of attraction in the above substances is described by which of the following:
dipole-dipole forces (permanent dipoles)
ion-dipole forces
London dispersion forces
gravitational forces
The boiling point of CH4 is much lower than that of HF. This is because:
of dipole-dipole interactions in CH4
HF is more polarizable
CH4 is polar
of hydrogen bonding in HF
Why is the normal boiling point of hydrogen fluoride is so much higher than that of hydrogen chloride, the hydride of the next element in group VIIA?
the HF molecules have a lower dipole moment.
HCl molecules are non-polar.
the HF molecules undergoes a higher degree of hydrogen bonding than HCl.
the electron cloud in the HF molecule is more easily distorted (i.e. is more polarizable) than that of HCl.
