Intramolecular forces of attraction are important in holding large molecules together. a. True
b. False

False. Intermolecular forces of attraction are important in holding large molecules together.

Explanation:

Within a molecule, atoms are held together by intramolecular forces. That is, intramolecular forces are the attractive forces that hold the atoms or ions that make up chemical substances (elements and compounds) together, forming a chemical bond.

On the other hand, intermolecular forces are those that act on different molecules or ions and that make them attract or repel each other. In other words, intermolecular forces are those that occur between the different molecules of a compound, and cause these molecules or ions to attract or repel each other.

So, intermolecular forces of attraction are important in holding large molecules together.
