Question

Arrange the following in increasing order of intermolecular forces

Answer 1

Among the given options, $H_{2}O$ and $CO$ are polar, therefore they will have stronger dipole interactions. On top of that, $H_{2}O$ has the capability of forming $H$-bond, due to which the $IMF$ will be the strongest in $H_{2}O$. The only $IMF$ in $C{O}_2,Ne$ and $He$ are London dispersion forces that would be highest for $C{O}_2$ than $Ne$ and lowest would be for $He$ due to its minimum mass.
