(a)
Interpretation:
Among the given substances, amorphous solid has to be identified.
Concept Introduction:
Amorphous solids lack such defined arrangement of its components instead disordered or random arrangement does exist in them. They are termed as pseudo solids or super cooled liquids. Example: Glass, Wood etc.
(b)
Interpretation:
Among the given substances, ionic solid has to be identified.
Concept Introduction:
In ionic solids, ions of opposite charges are bind together by electrostatic force and are neatly stacked to form a regular and well-defined structure. Example:
(c)
Interpretation:
Among the given substances, molecular solid has to be identified.
Concept Introduction:
Molecular solids are type of crystalline solids in which the molecules are linked by intermolecular forces. The solid structure is maintained by the intermolecular forces rather than bonds. The forces that holds the solids together are much weaker than for the other types of solids.
(d)
Interpretation:
Among the substance, covalent network solid has to be identified.
Concept Introduction:
In Covalent solids the components are atoms bonded by covalent bond repetitively and thus forms huge network form of solid. Network solids are widely formed by group 14 elements and its compounds. Example: Diamond, Amethyst.
(e)
Interpretation:
Among the given substances, metallic solid has to be identified.
Concept Introduction:
Metallic solids generally consist of metal atoms and the metal atoms are linked by metallic bonds. All the metals and their alloys are generally metallic solids.
