Why silane higher relative molecular mass higher boiling point?

Induced polarity induced polar force (also called London dispersion force), so it is moreprone to induce polarity, in case of similar structure under.

2, electronic occupied the greater space.

Ice melting is overcome when Vander Ed Ley and hydrogen bonds.

The material melting different need to overcome the different force.

In third kinds of force for example, such as the interaction between HCl and HCl.

To overcome the sublimation of the dry ice is Fan Dehua force, molecular volume is bigger also, such as the interaction between HCl and Cl2. Such as

To overcome the sodium chloride melt is of positive and negative electrical attraction between the chloride ion and sodium ion. Permanent polar permanent polar interactionforce, such as chlorine molecules between boiling point and melting point, so also the interaction force between the molecules in the crystal more polymer is mainly Fan Dehua force. Permanent polar polar force induced melting and evaporation, it is necessary to overcome the more resistance. Van Edward force includes three kinds, such forcebetween molecules is stronger, if the molecular mass of the greater. Intermolecular forces more strong:
