Which of the following molecules cannot form hydrogen bonding among themselves? A) CH₂O B) CH₃CHO C) (CH₃ – CH₂)₃N D) All of the above
- CH₂O
- CH₃CHO
- (CH₃ – CH₂)₃N
- All of the above
Explanation
The molecule that cannot form hydrogen bonding among themselves is All of the above.
Hydrogen bonding occurs when a hydrogen atom is bonded to a highly electronegative atom (oxygen, nitrogen, or fluorine) in one molecule and is attracted to the lone pair of electrons on another electronegative atom in a different molecule.
A) CH₂O (Formaldehyde):
While the oxygen is electronegative, the hydrogen is not directly bonded to it, so it cannot participate in hydrogen bonding.
B) CH₃CHO (Acetaldehyde):
Similar to A, the hydrogen is not directly bonded to the oxygen.
C) (CH₃ – CH₂)₃N (Trimethylamine):
Although the nitrogen is electronegative, the hydrogen atoms are not directly bonded to the nitrogen.
