Mistakes

100

What is the mistake?

"NaCl is sodium monochloride."

Sodium chloride

This compound is ionic, so the name does not have prefixes

200

What is the mistake?

"CaCO₃ is calcium carbon oxide."

It should be calcium carbonate

300

What is the mistake?

"H₂O is dihydrogen monoxide"

Its formal name even in chemistry is water.

400

What is the mistake?

"Co₃P₂ is cobalt phosphide"

Cobalt is a transition metal, so the name should be:

Cobalt(II) phosphide

500

What is the mistake?

"CH4 is carbon tetrahydride"

Its formal name is "methane"
