Answer:
C6H6 - organic compound
K - element
Cl2 - inorganic elemental molecule
SO2 - inorganic compound
Explanation:
An organic compound contains carbon and hydrogen bonded covalently . Sometimes other atoms aside from carbon and hydrogen called heteroatoms are also found in organic compounds. C6H6 is an organic compound.
Elements are found in periodic table. They always occur in uncombined state. K is an element.
Cl2 is an inorganic elemental molecule containing two chlorine atoms bonded covalently.
SO2 is an inorganic compound composed of sulphur and oxygen bound covalently. Mnay inorganic compounds do not contain carbon
