SiH4 and CH4
The only intermolecular force they both have is London Dispersion forces
Strength of LDF is determined by molar mass
molar mass of SiH4 = 32.132
molar mass of CH4 = 48.42
Therefore shouldn't CH4 have a stronger LDF??
The answer says that SiH4 has a greater intermolecular force...why is that?
