WebWhy is Methane’s Boiling Point Higher than Neon’s? A methane molecule is larger than a neon atom. Because the electrons in methane molecules are dispersed over a larger area and their distribution (in space) is easier to distort, methane is more polarizable and the dispersion forces are greater. Let me clear this up for you (other posters ... WebMelting point. The melting points of the alkanes follow a similar trend to boiling points for the same reason as outlined above. That is, the larger the molecule the higher the melting point. There is one significant difference between boiling points and melting points. Solids have a more ridged and fixed structure than liquids.

Methane is a tetrahedral molecule with four equivalent C–H bonds. Its electronic structure is described by four bonding molecular orbitals (MOs) resulting from the overlap of the valence orbitals on C and H. The lowest-energy MO is the result of the overlap of the 2s orbital on carbon with the in-phase combination of the 1s orbitals on the four hydrogen atoms. Above this energy level is a triply degenerate set of MOs that involve overlap of the 2p orbitals on carbon with vari… Web14 hours ago · Avner Gross. Apr 14, 2024 2:05 am IDT.
