Which of the following will not form H-bond with another of its own molecule?
Correct answer: A. CH3CHO
- A. CH3CHO
- B. CH3NH2
- C. CH3OH
- D. NH3
Explanation
Option A is correct.CH3CHO (acetone) will not form hydrogen bonds with another molecule of itself. Hydrogen bonding is a type of intermolecular force that occurs between a hydrogen atom that is covalently bonded to a highly electronegative atom, such as oxygen, nitrogen, or fluorine, and another atom that has a lone pair of electrons. The hydrogen atom is attracted to the lone pair of electrons, and this attraction creates a weak bond between the two atoms. In acetone, the hydrogen atoms on the two methyl groups are not bonded to any electronegative atoms. Therefore, they cannot form hydrogen bonds with other acetone molecules.

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.
