GeCl$_4$ has the strongest IMF. SiCl$_4$ has the 2nd strongest IMF. SiH$_4$ has the 3rd strongest and CH$_4$ has the weakest IMF out of the four.
Work Step by Step
Calculating the strongest IMF based of type of IMF, hydrogen bonding being the strongest and dispersion forces the weakest. Molecular weight affects dispersion forces, the heavier the molecule the stronger the dispersion force.
