D.Phosphorus
Solution
(i) I2 is molecular solid in which I2 molecules are interacted by weak London forces.
(ii) Silicon exists in diamond like structure in which atoms of Si are bonded by covalent bond. Hence it is a covalent solid.
(iii) Sulphur is molecular solid in which S8 molecules are interacted by London force.
(iv) White phosphorous is a molecular solid in which P4 molecules are interacted by London force.
