The following molecules have double covalent bonds between two atoms except?
Answer Details
All of the molecules listed have at least one double covalent bond between two atoms except for water.
A covalent bond is a type of chemical bond where atoms share electrons to achieve a stable configuration. A double covalent bond occurs when two pairs of electrons are shared between two atoms.
Oxygen has a double covalent bond between two oxygen atoms (O=O).
Carbon (IV) oxide, also known as carbon dioxide, has a double covalent bond between one carbon atom and two oxygen atoms (O=C=O).
Ethene, also known as ethylene, has a double covalent bond between two carbon atoms (C=C).
Water, on the other hand, has two single covalent bonds between one oxygen atom and two hydrogen atoms (H-O-H). It does not have any double covalent bonds.
In summary, all the listed molecules have double covalent bonds between two atoms except for water, which has only single covalent bonds.
