Polymers and giant covalent structures Flashcards
What is a polymer?
Long chains of repeating units
What are atoms in a ploymer joined by?
Strong covalent bonds
The intermolecular forces between polymer molecules are larger than between simple covalent molecules so…
more energy is needed to break them. This means most polymers are solid at room temperature.
What are the intermolecular forces in polymers like compared to ionic and covalent bonds?
The intermolecular forces are still weaker than ionic or covalent bonds , so they genuinely have lower boiling points then ionic or giant molecular compounds.
In giant covalent structures how are all the atoms bonded together?
by strong covalent bonds
Descibe there melting and boiling points
They have very high melting and boiling points. Lots of energy is needed to break them
Are they good conductors?
Most dont conduct electricity as they dont contain charged particles-not even when molten(except graphite)
Name 3 Gaint covalent structures:
-Diamond (made of carbon)
-Graphite (made of carbon)
-Silicon dioxide
