The melting and boiling points of carbon compounds are generally low and they are largely non-conductors of electricity. State two conclusions based on these two properties.
Marking-scheme solution
Low melting points and boiling points - Weak intermolecular forces of attraction.
Non-conductors of electricity - Bonding in these compounds does not give rise to any ions. / Covalent bonds or sharing of electrons do not form any charged particles.
