The diagrams above represent two allotropes of solid phosphorus. Which of the following correctly identifies the allotrope with the higher melting point and explains why?
Allotrope I, because it has P4 molecules with covalent bonds that are stronger than dispersion forces between individual P atoms in allotrope II.
Allotrope II, because it has covalent bonds between the phosphorous atoms that are stronger than the dispersion forces between the P4 molecules in allotrope I.
Allotrope II, because it has metallic bonding that is stronger than the covalent bonding found in the P4 molecules in allotrope I.
Both allotropes have the same melting point because they both contain phosphorous atom
