Elemental phosphorus is a molecular solid consisting of P₄ molecules.It melts at 44°C.What is the principal force present in P₄(s)?

Question

Quizplus · Accepted Answer

Elemental phosphorus is a molecular solid, meaning it consists of discrete molecules held together by covalent bonds. The principal force present in such a substance is dispersion forces, which arise from temporary fluctuations in electron density that cause instantaneous dipoles in neighboring molecules. While there may be some small dipole moments in P₄, they are not strong enough to be considered the principal force. Hydrogen bonding requires hydrogen atoms bonded to highly electronegative atoms like oxygen or nitrogen, which is not the case in P₄. Metallic bonding and ionic bonding are not present in molecular solids like P₄.
