Respuesta :
The diatomic molecule that forms a double covalent bond has been [tex]\rm \bold O_2[/tex]. Thus, option A is correct.
The double covalent bond has been a unsaturated bond with the presence of 1 sigma and 1 pi bond. The valence electrons of the atoms has been shared in between the atoms for the completion of the octet of atoms, and achieve as a stable molecule.
The double covalent bond has been present in the diatomic molecules that requires 2 electrons by both the atoms for octet completion. The valence electrons in this molecule has been 6.
The valence electrons in the following compounds has been:
Oxygen = 6
Chlorine = 7
Nitrogen = 5
Helium = 0
The molecule with the presence of 6 valence electrons has been oxygen. Thus, the diatomic molecules with double covalent bond is Oxygen. Option A is correct.
