Consider the following list of molecules: O2, H2O2, HF, N2, CO, NO, F2 Out of the list above, how many of the molecules could be classified as a “homonuclear diatomic”? A. 1 B. 2 C. 3 D. 4 3
Ans: C) 3
Diatomic Molecules: The molecules that are composed of only Two Atoms are called Diatomic Molecules.
HomoNuclear Diatomic Molecules: If both the atoms of a Diatomic Molecule are same, then it can be called as HomoNuclear Diatomic Molecule. In a HomoNuclear Diatomic Molecule, the bond in Non-Polar.
The possible HomoNuclear Diatomic Molecules are:
Hydrogen (H2)
Nitrogen (N2)
Oxygen (O2)
Fluorine (F2)
Chlorine (Cl2)
Iodine (I2)
Bromine (Br2)
Hence, from the options given, the answer is (3) : Nitrogen, Oxygen and Flourine Gases (N2, O2, F2)
