Word: Hydrogen Bond

Part of Speech: Noun

Definition: A hydrogen bond is a special type of connection that forms between a hydrogen atom and two other atoms, usually those that are very good at attracting electrons, called electronegative atoms (like oxygen or nitrogen). In this bond, one side involves a covalent bond (where atoms share electrons), and the other side is more like an ionic bond (where atoms attract each other because of their opposite charges).

Usage Instructions

• When to Use: You can use the term "hydrogen bond" when talking about chemistry, especially in the context of how molecules interact with each other.
• Where to Use: This term is commonly used in science classes, research papers, or discussions about biology and chemistry.

Example

• Water (H₂O) has hydrogen bonds between its molecules, which help water stay liquid at higher temperatures than it would otherwise.

Advanced Usage

In advanced chemistry, you might discuss hydrogen bonds in terms of their strength and how they affect the properties of substances, like boiling points and solubility.

Word Variants

• Hydrogen Bonding (noun): Refers to the process or phenomenon of forming hydrogen bonds.
• Hydrogen Bonded (adjective): Describes molecules that are connected through hydrogen bonds.

Different Meanings

In a non-scientific context, "hydrogen bond" does not have other meanings. It is a specific term used in chemistry.

Synonyms

There are no direct synonyms for "hydrogen bond," as it is a specific term in chemistry. However, you might refer to it as a "weak bond" in a general sense, but this is not technically accurate.

Idioms and Phrasal Verbs

There are no idioms or phrasal verbs that directly relate to "hydrogen bond," as it is a scientific term. However, in casual conversation, people might use phrases like "bonding over" to describe forming connections, but this is not related to the chemical term.

Summary

A hydrogen bond is an important concept in chemistry that describes how certain atoms, especially hydrogen, connect with other atoms.
