    Hope it's ok if I put out a statement: 'Graphite is soft and slippery due to weak Van der Waals' (intermolecular) forces in the tetrahedral structure'

    Hmm, it kind of is (but it doesn't have a tetrahedral structure, that's diamond, it's cos of weak forces between the layers) but I didn't know van der Waarl's were for GCSE :holmes:

    Yeah, it's false because it's not a tetrahedral structure (hexagonal layers, 3 C-C bonds) and, as you said, the weak intermolecular forces are between the layers, making them easily slide.

    And you're right, you don't need to know about Van der Waals' forces (hence why I put 'intermolecular' in brackets), but I just think they're interesting and more specific

    True - maybe not the 'all revealed' bit but it's usually when everything in the plot is wrapped up at the end.
