A coordinate bond is one in which:
ABoth electrons of the shared pair come from one atom
BElectrons are transferred completely
CElectrons are shared equally
DNo electrons are shared under typical conditions
Answer & Solution
Correct answer: A. Both electrons of the shared pair come from one atom
1. In a coordinate (dative) bond one atom supplies both bonding electrons.
2. The other atom contributes an empty orbital.
3. Once formed, it behaves like a regular covalent bond.
4. Example: NH4+ has one coordinate bond.
