Simple molecular substances

Question 1

Substances containing __________________ usually have simple molecular structures

Answer 1

Covalent bonds

Question 2

Simple molecular substances have strong covalent bonds, but in contrast…

Answer 2

The intermolecular forces of attraction between these molecules are very weak

Question 3

What happens when melting or boiling a simple molecular compound?

Answer 3

Intermolecular forces are broken and covalent bonds are not

Question 4

What state are they mostly at room temperature?

Answer 4

gases or liquids at room temperature

Question 5

What happens as the intermolecular forces get bigger?

Answer 5

The strength of the intermolecular forces increase, so more energy is needed to break them and the melting and boiling point increases.

Question 6

Why dont molecular compounds conduct electricity?

Answer 6

Dont conduct electricity , they have no charge (they are neutral) so there are no free electrons or ions.
