Question

Which of the following is a triatomic molecule? a) Glucose b) Helium c)Carbon dioxide d) Hydrogen

Answer 1

Answer:

here is your answer

Explanation:

(c) . carbon dioxide ( CO2) is right option.

Answer 2

C. Carbon dioxide is a triatomic molecule.

Definition of Triatomic molecule:

• A triatomic molecule is a molecule that is formed by three atoms, of either the same or different chemical elements.
• Such molecules are formed by combining three atoms in order to form a single compound.

Justification of Answer:

1. Option A. Glucose: The chemical formula for Glucose is $C_{6}H_{12}O_{6}$. This means that glucose is formed by combining 24 atoms. Thus, it is not a triatomic molecule.
2. Option B. Helium: The chemical formula for Helium is $He$. This means that it contains only one single atom. Thus, it is not a triatomic molecule.
3. Option C. Carbon dioxide: The chemical formula for Carbon dioxide is $CO_{2}$. This means that it contains three atoms and hence is a triatomic molecule.
4. Option D. Hydrogen: The chemical formula for Hydrogen is $H.$ his means that it contains only one single atom, and is not a triatomic molecule.

Hence, Carbon dioxide is a triatomic molecule as it is formed by combining 3 atoms.
