  • Q:

    What are the properties of organic and inorganic compounds?

    A:

    Inorganic compounds form ionic bonds, have high melting points and are made from either single elements or compounds that do not include carbon and hydrogen. In solutions, they break down into ions that conduct electricity. Organic compounds have a carbon-based structure with covalent bonding and are often volatile in nature. Even in liquid state, they do not conduct electricity unless they are salts formed with inorganic acids and bases.
