Chapter 11, Problem 11.77QP

Interpretation Introduction

Interpretation:

The given substances have to be listed in order of increasing melting point.

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 solid
• 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 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.

Diamond and graphite are great example.
