Question 1 Report
The following molecules have double covalent bonds between two atoms except?
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.
