White phosphorus, P4P_4P4, is a molecular solid that melts at a relatively low temperature of 44.1∘C44.1^\circ\text{C}44.1∘C to form a liquid containing P4 P_4\,P4 molecules.
Which statement correctly explains why white phosphorus has a low melting point?
The covalent bonds between the phosphorus atoms within the P4P_4P4 molecules are weak and easily broken.
There are weak intermolecular forces holding individual phosphorus atoms together in the lattice.
There are weak intermolecular forces between the P4P_4P4 molecules, which require little energy to overcome.
There are weak ionic attractions between the P4P_4P4 molecules that are easily disrupted by heating.
