MCQ
A coordinate bond is formed when an atom in a molecule has
- AElectric charge on it
- BAll its valency electrons shared
- CA single unshared electron
- ✓One or more unshared electron pair
✓
Answer
Correct option: D.
One or more unshared electron pair
d
A co-ordinate or dative bond is a covalent bond(a shared pair of electrons) in which both the electrons come from the same atom. It is shown by an arrow and the arrow points from atom donating the lone pair to accepting atom.
