Question

which of the following is a diatomic molecules A)Co B)Co2 D)So3 C)Po4​

Answer 1

See you gotta clear the concept, Di means two and atomic means atom, so if there are two atom in molecule than it’s diatomic-
Eg- H2, Is diatomic molecule,

Co, is diatomic in this as there is one atom of Carbon + one atom of oxygen = 2 atoms

Answer 2

(a) CO is a diatomic molecule.

• A diatomic molecule is a molecule that consists of only two atoms in its structure.
• Diatomic molecules' examples are hydrogen, oxygen, nitrogen, carbon monoxide, etc.
• The first option is carbon monoxide which is a diatomic molecule as it contains only one carbon and one oxygen atom.
• Option B is carbon dioxide which contains three atoms in its structure.
• Option C is phosphorus tetraoxide which consists of five atoms in its structre.
• Option D is sulphur trioxide which contains four total atoms in its structure.
