There are also transitional types of keys: one key electronic bias is called polar covalent bond, the bonding electrons provided by the party known 翻译结果3复制译文编辑译文朗读译文返回顶部 Positioning in the key between 2 atoms called a domain key. Formed by more than one atom of a total ...
Hydrogen bonds: Hydrogen bonds are formed as a result of the attractive force occurring between a hydrogen atom which is already covalently bonded to a very electronegative atom like oxygen, fluorine, or nitrogen and another very electronegative atom like those. This other atom can be oxygen...
chloroform(CHCl3): Hydrogen bonding occurs between hydrogen of one molecule and carbon of another molecule. ammonia(NH3): Hydrogen bonds form between hydrogen of one molecule and nitrogen of another. In the case of ammonia, the bond that forms is very weak because each nitrogen has one lone el...
Water is a polar molecule, while carbon tetrachloride is a nonpolar molecule. If we use the 'like dissolves like' concept, then acetone is both polar and nonpolar. This dual character of acetone isdue to its ability to make hydrogen bonds with water and the presence of two methyl groups. ...
Hydrogen Bonding Polar covalent bonds such as those found in water allow the formation of hydrogen bonds, a weak attractive force between the slight negative charge in one polar molecule and the slight positive charge in an adjacent polar molecule. While the individual hydrogen bonds are weak, the...
单选题 Which of the following bonds attracts atoms of hydrogen to each other in a H2 molecule? A、 hydrogen bonding. B、 ionic bonding. C、 metallic bonding. D、 non-polar covalent bonding. E、 polar covalent bonding. 查看答案 单选题 When the electrons are shared unequally by two atoms...
The bond between the hydrogen and oxygen in a water molecule would be classified as polar covalent. As a full molecule, the two polar bonds leads to an polar molecule as a whole. What is polar and nonpolar? Polar and non-polar refers to the level in which two elements equally share a ...
The H2O water molecule is polar with intermolecular dipole-dipole hydrogen bonds. As the water molecules attract each other and form bonds, water displays properties such as high surface tension and a high heat of vaporization. Intermolecular forces are much weaker than the intramolecular forces that...
Water boils when the energy from the heat is great enough to break the hydrogen bonds between the water molecules. The gas that is released from the boiling water is made up of oxygen and carbon dioxide. If you’ve ever boiled water, you will have noticed that as water heats up, very ...
Examples of weak chemical bonds include dipole-dipole interactions, the London dispersion force, Van der Waals and hydrogen bonding. In the abovementioned polar covalent bond, the sharing of electrons is not equal. When two such molecules come into contact and are oppositely charged, there is a ...
