Question

Classify the following compounds as diatomic,triatomic and polyatomic molecules. HCl, H2, H2O, NH3, CH​3OH, ​PCl5

Answer 1

HCL=monoatomic
H2=diatomic
H2O=di atomic
NH3=triatomic
CH3OH=mono atomic
PCL5=triatomic

Answer 2

The classification of the given compounds is given below:

1. Diatomic molecules: These molecules have exactly two atoms bonded together by a chemical bond. Example: HCl (Bond between 1 H atom and 1 Cl atom), H₂ (Bond between 2 H atoms).
2. Triatomic molecules: They have exactly three atoms in their molecule. Example: In H₂O two hydrogen atoms and one oxygen atom covalently bond to form a water molecule.
3. Polyatomic molecule: NH₃, CH₃OH, and PCl₅ have 4, 6, and 6 atoms in their molecules respectively.
