Which of the following is not a primary bond?
Correct answer: B. Hydrogen bond
- A. Ionic bond
- B. Hydrogen bond
- C. Dative bond
- D. Covalent bond
Explanation
Ionic bond is a type of primary bond because an ionic bond is formed when valence electrons are transferred from atom to another to complete the outer electron shell.Hydrogen bond is the stronger form of secondary bonding and is formed from polar molecular bonding. It is not a type of primary bond.The dative (coordinate covalent bond) is a type of primary bonding in which the two electrons derive from the same atom.The covalent bond is the primary type of bonding because it forms when one or more pairs of valence electrons are shared between atoms. Hence, option B is correct.

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.
