Polymers And Giant Covalent Structures

Question 1

What are polymers?

Answer 1

Large molecules made up of repeating units bonded together as long chains

Question 2

What state are most polymers at room temperature?

Answer 2

Most polymers are solid at room temperature. This is because the intermolecular forces between the polymer molecules are relatively strong so more energy is needed to break them.

Question 3

Why do polymers have lower boiling and melting points than ionic or giant molecular compounds?

Answer 3

Although the intermolecular forces between the polymer molecules are relatively strong, they are still weaker than ionic or covalent bonds.

Question 4

What are giant covalent structures?

Answer 4

all atoms are bonded together by strong covalent bonds

Question 5

What is silcone dioxide?

Answer 5

-an example of a giant covalent structure also known as silica (what sand is made up of)
-made up of silicone and oxygen
