Which of the following molecules / lons contains coordinate covalent bond |
|
Answer» n-rich and electron-deficient atoms. It is best for ammonia and carbon dioxide.Explanation:A Coordinated bond is formed between electron-rich and electron-deficient atoms. The donor atom should have at least one lone pair of electrons and the ACCEPTOR atom should have at least one vacant orbital.In NH₄⁺, the nitrogen in NH₃ is electron-rich and H⁺ ions do not any electron. Thus nitrogen from NH₃ shares a pair of electrons with H⁺ to make a coordinate bond.Each of the covalent bonds that we have looked at so far has involved each of the atoms that are bonding contributing one of the electrons to the shared pair. There is an alternate type of covalent bond in which one of the atoms provided both of the electrons in a shared pair. Carbon MONOXIDE, CO, is a toxic gas that is released as a by-product during the burning of fossil fuels. The bonding between the C atom and the O atom can be THOUGHT of as proceeding in this way. |
