Naming Molecular Compounds

When naming salts, do we ever say the number of cation and anions? No! When naming molecular compounds, do we say the number of atoms of each element Usually we do. But we say the numbers in Greek One is mono Six is Two is di Seven is hepta hexa Three is tri Eight is octa Four is tetra Nine is nona Five is penta Ten is deca

Let’s practice the Greek number system. Greek English mono one tetra four tri three hepta seven hexa six penta five deca ten octa eight di two nona nine

Let’s practice the Greek number system. English Greek five penta one mono seven hepta nine nona six hexa three tri eight octa two di four tetra ten deca

Using these greek numbers, name the following compounds: One is mono Three is tri Two is di Five is penta Seven is hepta Four is tetra Six is hexa Eight is octa Nine is nona Ten is deca SCl 2 – one sulfur & two chlorines sulfur dichloride PCl 3 – one phosphorus & three chlorines phosphorus trichloride PCl 5 – one phosphorus & five chlorines phosphorus pentachloride CO 2 – one carbon & two oxygens CO – one carbon & one oxygen NO 2 – one nitrogen & two oxygens carbon dioxide carbon monoxide nitrogen dioxide SO 3 – one sulfur & three oxygens sulfur trioxide N 2 O 5 – two nitrogens & five oxygens dinitrogen pentoxide

Using these greek numbers, give formulas for the following names: One is mono Three is tri Two is di Five is penta Seven is hepta Four is tetra Six is hexa Eight is octa sulfur hexachloride SCl 6 nitrogen trichloride NCl 3 oxygen difluoride OF 2 bromine trifluoride Br. F 3 diiodine tetroxide I 2 O 4 dinitrogen monoxide N 2 O sulfur dioxide SO 2 dinitrogen tetroxide N 2 O 4 Nine is nona Ten is deca
