(a)
Interpretation:
In each of the given pairs of substances which one has lower melting point has to be explained.
Concept introduction:
Melting point:
The temperature at which a crystalline solid melts into a liquid is known as melting point.
Both melting point and boiling points are characteristic properties of the compound.
Types of solids give melting points of several substances.
Types of solid
- Molecular soli
- Metallic solid
- Ionic solid
- Covalent network
Molecular solid:
A solid which consist of atoms or molecule thought intermolecular force.
Metallic solid:
The solid which consist of metal atom held together by metallic bonds. Metallic bonding is
Ionic solid:
A solid which consist of anions and cations held together by ionic bond (electrical attraction of opposite charges).
Covalent network:
A solid that involves atoms held together by great network or shackles by covalent bonds.
Diamond and graphite are great example.

Metallic solid:
The solid which consist of metal atom held together by metallic bonds. Metallic bonding is chemical bond formed by attraction between cation of metal and the surrounding sea of electrons.
Ionic solid:
A solid which consist of anions and cations held together by ionic bond (electrical attraction of opposite charges).
Covalent network:
A solid that involves atoms held together by great network or shackles by covalent bonds.
