If two atoms are bonded in such a way that one member of the covalently bonded molecule donates both electrons that are shared, then what is this type of bond called?
Correct answer: C. Coordinate covalent bond
- A. H-bonding
- B. Covalent bond
- C. Coordinate covalent bond
- D. Electrovalent bond
Explanation
A coordinate covalent bond, also known as a dative bond or a Lewis acid-base bond, is formed when one atom (the donor) provides both electrons for sharing with another atom (the acceptor). This type of bond is often indicated by an arrow pointing from the donor atom to the acceptor atom.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
