text: Hydrogen bonds have about a tenth of the strength of an average covalent bond, and are being constantly broken and reformed in liquid water.
text: Whether a hydrogen bond is considered broken or just stretched or bent should be defined by its strength but, as the isolated bond strength may be difficult to determine, this often remains a matter of an arbitrary definition based on distances and angles.
text: Covalent bonds are hard to break because doing so requires a lot of energy, but hydrogen bonds are weak enough to be broken relatively easily.
text: Some researchers consider the hydrogen bond to be broken if the bond length is greater than 3.10 Å or the bond angle less than 146° .
text: If a hydrogen bond is broken, the two members will form alternative hydrogen bonds with the surrounding solvent – water.
text: Hydrogen bonds have about a tenth of the strength of an average covalent bond, and are being constantly broken and reformed in liquid water.
text: Hydrogen bonds have about a tenth of the strength of an average covalent bond, and are being constantly broken and reformed in liquid water.
text: They are almost always immediately formed again (in liquid), but the more frequently they are broken, the less hydrogen bonding there will be on average.
text: The hydrogen bond can be considered broken with O-H H····O bond length differences varying with the bond angle (180° 1.67 Å; 135° 1.53 Å; 90° 1.40 Å).
