Why is the boiling point of a iodoalkane greater than that of the corresponding fluoroalkane?
Why is the boiling point of ethyl iodide (b.p. 72 °C) higher than the boiling point of ethyl fluoride (b.p. −37 °C) even though the dipole–dipole interaction should be better in $\ce{C2H5F}?$ Is it ...

Order of boiling point of group 14 halides
Find out the species having lowest boiling point:
(A) $\ce{SnCl4}$
(B) $\ce{GeCl4}$
(C) $\ce{SiCl4}$
(D) $\ce{CCl4}$
I have considered the inert pair effect of $\ce{Sn}$ here which will make the ...

Does the van der Waals force not affect the alkali metal 's trend of decreasing melting points down the table? [duplicate]
Melting and boiling points increase further down the halogen group, but they decrease further down the alkali metal group. I know that the former's trend has to do with the van der Waals force, but I ...

Why does AsF3 boil at 60.4 Celsius and AsF5 at -52.8?
I don't understand why the boiling point of $\ce{AsF3}$ is at 60.4 degrees Celsius and $\ce{AsF5}$ boils at -52.8 degrees Celsius. I understand that it has to do with the bondings, but I can't see ...

Why is the boiling point of alkyl iodide is more than alkyl fluoride?
As far as I know, the more the polar nature of the organic compound, the more will be the energy required to break the intermolecular bonds and thus a higher boiling point. Here in this case, $\ce{R-F}...

Why do chlorinated silanes have lower boiling points than their methane analogs?
The boiling points of the chlorinated silanes and methanes are given below:
$$\begin{array}{ccc}
\hline
\text{Species} & \text{Boiling point (X = Si) / }\mathrm{^\circ C} & \text{Boiling ...

Why do the boiling and melting points decrease as you go down group 1 and vice versa for group 7?
I used to think that because an alkali metal needs to lose one electron to complete its outer shell, when the atom increases in size (atomic radius), the electron would be easier to lose as the ...

Why does tetrachloromethane have a higher boiling point than trichloromethane?
London dispersion forces (LDF) are present in all molecules, whether polar or non-polar. Molecules also exhibiting dipole-dipole interactions (in addition to the LDF) must have stronger forces of ...

Comparison of boiling points
I was comparing boiling points of $\ce{CHCl_3}$ and $\ce{CH_3Cl}$. According to me B.P. of $\ce{CHCl_3}$ should be higher due to it's higher molecular mass than $\ce{CH_3Cl}$, but the answer is ...
