_ is also known as a dative bond.
Correct answer: C. Coordinate covalent bond
- A. Ionic bond
- B. Covalent bond
- C. Coordinate covalent bond
- D. Metallic bond
Explanation
Option C is correct. A coordinate covalent bond is also known as a dative bond. A coordinate covalent bond is a type of covalent bond in which both electrons are donated by the same atom. This type of bond is often formed between a Lewis acid and a Lewis base. A Lewis acid is an atom or molecule that can accept a pair of electrons. A Lewis base is an atom or molecule that can donate a pair of electrons. In a coordinate covalent bond, the Lewis acid donates a pair of electrons to the Lewis base. The Lewis base accepts the pair of electrons, and a covalent bond is formed.

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.
