Hydrogen bond in waterThe most ubiquitous, and perhaps simplest, example of a hydrogen bond is found between water molecules. In a discrete water molecule, water has two hydrogen atoms and one oxygen atom. Two molecules of water can form a hydrogen bond between them. The oxygen of one water...
In the compound, H2O, the electrons in the bonds are unequally shared between oxygen and hydrogen, forming what? Which of the following bonds would be covalent but not polar covalent, that is, a nonpolar covalent bond? a. Al-S b. Ge-As c. K-F d. N-O ...
Intramolecularhydrogen bonds occur within different groups of asinglemolecule (e.g.,between the two hydroxyl groups of ethylene glycol). The hydrogen donor and acceptor atoms must be located close to each other within the same molecule. Intermolecularhydrogen bonds occur between two or moreseparate, ...
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 oxyg...
For example, water can be decomposed through electrolysis, the result of the process being O2 and H2.Now, if the hydrogen and oxygen I stored are both in an enclosed space and exposed to a flame, the result will be a violent exothermic reaction (an explosion) AND water. So through this...
Notice that the bonds occur between the weakly positive charge on the hydrogen atoms and the weakly negative charge on the oxygen atoms. Hydrogen bonds are relatively weak, and therefore are indicated with a dotted (rather than a solid) line. The most common example of hydrogen bonding in the...
Which of the following covalent bonds is the least polar? (EN values: H: 2.1; B: 2.0; C: 2.5; N: 3.0; O: 3.5) A) A covalent bond between hydrogen and boron B) A covalent bond between hydrogen and carbon C) A covalent bond between hydrogen and...
Hydrogen bonds are weak bonds that form between molecules. These bonds always include hydrogen and are due to electrostatic forces that cause attractions between molecules. Water is an example of a molecule that forms hydrogen bonds.Answer and Explanation: ...
Carbon atoms are black, oxygen atoms are red, and hydrogen atoms are not shown. The unit cell is indicated (blue lines) and the distance between two cellulose chains situated in the corners of the unit cell is 0.817 nm, indicated by the bar below the structure. Dashed lines indicate ...
