The alkanes are a homologous series with a structure based on a carbon chain - each carbon atom forms four covalent bonds The intermolecular forces vary between molecules, so different organic ...

Covalent Bond: They are formed by sharing of electrons and have low melting and boiling point. These are soluble in organic solvents and are non-conductor of electricity. However graphite and diamond ...
