Chemistry
An example of a double covalent bond is:
- Nitrogen molecule
- Hydrogen molecule
- Oxygen molecule
- Chlorine molecule
Answer
Oxygen molecule
Reason — To attain the stable electronic configuration of the nearest noble gas neon, oxygen needs two electrons.
When two oxygen atoms come closer, each contributes two electrons and so they have two shared pairs of electrons between them. Both atoms attain an octet, resulting in the formation of a double covalent bond [O=O] between them.
Nitrogen molecule forms a triple covalent bond. Hydrogen molecule forms a single covalent bond. Chlorine molecule forms a single covalent bond.
