The polymer moieties have a valence orbital bond to the carbonaceous particulate, such as an ionic or covalent bond. |
|
The particles have functional sites for forming a hydrogen bond or a coordinate covalent bond. |
|
Electronegativity can be used to predict whether a bond will be a nonpolar covalent bond, a polar covalent bond, or an ionic bond. |
|
These rules are the result of assigning all electrons in a covalent bond to the more electronegative atom in the bond. |
|
The three shared pairs of electrons between the two carbon atoms create a triple covalent bond. |
|
In this case a covalent bond has an ionic component and is generally called a polar bond. |
|
In chemistry, a polar bond is a type of covalent bond between two atoms or more in which electrons are shared unequally. |
|
A polar bond can be thought of as intermediate between a covalent bond and an ionic bond. |
|
In a coordinate covalent bond, both electrons are donated by the Logan, a Lewis base, to the metal atom, a Lewis acid. |
|
In both cases, the ammonia molecule is acting as a Lewis base, donating the pair of electrons required to form the coordinate covalent bond. |
|
Thus conjugation can occur in molecules in which the unsaturated sites are close in space but are separated by more than a single covalent bond. |
|
This electrostatic attraction, called an ionic bond, is much weaker than a covalent bond of shared electrons. |
|
For example, electrons in a covalent bond are assigned to the more electronegative atom. |
|
To complete an octet, each oxygen must share two electrons in a covalent bond. |
|
Opposing this tendency is the covalent bond holding the HCl molecule together. |
|
Compared to say, a covalent bond, a hydrogen bond is approximately one tenth of that strength. |
|
Reactive dyeing directly links the colorant to the fibre by formation of a covalent bond. |
|
Many dye-fibre interactions, however, do not involve covalent bond formation. |
|
The d-orbitals form a covalent bond with the d-orbitals on the neighbouring atoms. |
|
A covalent bond is a bond formed when two atoms share a pair of electrons. |
|
|
The perpetual spin of an electron is an important aspect of the covalent bond. |
|
Due to its inherent chemical characteristics, only part of the dye that is introduced into the dye bath reacts chemically with the fibre by means of a covalent bond. |
|
The year 2016 then, marks the 100th anniversary of Lewis's concept of the covalent bond model and electron pairs. |
|
Each shared electron pair constitutes a covalent bond. |
|
While for covalent bond this ratio increases with bond strength. |
|
It exerts its therapeutic activity nonsystemically in the lumen of the stomach and small intestine by forming a covalent bond with the active serine site of gastric and pancreatic lipases. |
|
It should be emphasized that the difference in electronegativities, not the absolute electronegativity values, determines whether a covalent bond is polar or nonpolar. |
