Chapter 14, Problem 7STP

Interpretation Introduction

Interpretation:

The type of solid of table sugar needs to be determined.

Concept Introduction :

Sugar is the used as a sweetener; the main component present in the sugar is sucrose. The other names of sugar are table sugar, granulated sugar or regular sugar.

Sucrose is a disaccharide composed of glucose and fructose.

The chemical formula is ${\text{C}}_{\text{12}}{\text{H}}_{\text{22}}{\text{O}}_{\text{11}}$ . Each sugar molecule has $12$ carbon atoms, $11$ oxygen atoms, and $22$ hydrogen atoms.

Answer to Problem 7STP

D

Explanation of Solution

Table sugar is molecular solid because atoms or molecules of table sugar are held together by London dispersion forces and it has low melting point.

Conclusion

• Table sugar is not an atomic solid because Atomic solid has the atom of an element bonded to other atoms of the same atom type.
• Table sugar is not an ionic solid as there are no charged or polar parts to interact with.
• Network solids have high melting point, hence table sugar is not a network solid.
