Hydrogen Bonding and Common Mistakes

TL;DR

Hydrogen bonds form between different molecules, primarily between hydrogen and oxygen, fluorine, or nitrogen atoms.

Transcript

Hydrogen bonding can be so confusing, so I want to talk about some common mistakes people make so you won't ever make them. Okay, so hydrogen bonds are a type of intermolecular bond. Intermolecular bonds form between molecules, that's why we call them intermolecular. Now this "between" part is super important. Between two different molecules, I'm u... Read More

Key Insights

• 🙅 Hydrogen bonds form between different molecules, specifically between hydrogen (H) and oxygen (O), fluorine (F), or nitrogen (N) atoms.
• 💁 Hydrogen bonds cannot form within the same molecule.
• 🫀 The unequal sharing of electrons between the atoms involved in a hydrogen bond creates a positive and negative charge that attracts them to each other.
• 🫀 Hydrogen bonds are not possible between hydrogen and carbon (C) atoms.
• 🇧🇦 Hydrogen bonds can occur with multiple combinations, including H-O, H-F, and H-N.
• 🫀 Oxygen, fluorine, and nitrogen are the primary atoms involved in hydrogen bonding.
• ❓ Hydrogen bonding is a significant concept in understanding the properties and behavior of molecules.

Questions & Answers

Q: How do hydrogen bonds differ from other types of intermolecular bonds?

Hydrogen bonds specifically form between different molecules, while other intermolecular bonds can occur within the same molecule.

Q: Can any hydrogen bond with any other atom?

No, for hydrogen bonds to form, the hydrogen must be bonded to an oxygen (O), fluorine (F), or nitrogen (N) atom.

Q: Why can't hydrogen bonds form between a hydrogen and a carbon (C) atom?

Hydrogen bonds require an unequal sharing of electrons, which is not possible with a hydrogen and carbon bond because the electrons are shared equally.

Q: Can any hydrogen attached to an oxygen, fluorine, or nitrogen atom form a hydrogen bond?

Yes, any hydrogen attached to an O, F, or N atom on one molecule can form a hydrogen bond with an O, F, or N atom on another molecule.

Summary & Key Takeaways

• Hydrogen bonds are a type of intermolecular bond that form between different molecules.

• To identify hydrogen bonds, it is important to determine if the bond is between different molecules.

• Hydrogen bonds in ethanol molecules typically form between an hydrogen (H) attached to oxygen (O) and another O on a different molecule.
