Which of the following bonds is not present in NH4OH:
Correct answer: D. Delocalized covalent bond
- A. Ionic bond
- B. Coordinate covalent bond
- C. Covalent bond
- D. Delocalized covalent bond
Explanation
There are no delocalized covalent bonds in NH4OH. In NH4OH, the bonding involves the formation of ions. The nitrogen and hydrogen atoms form an ammonium ion (NH4+), and the oxygen and hydrogen atoms form a hydroxide ion (OH-), and these ions are held together by ionic bonds. There are no delocalized covalent bonds in this compound.

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.
