Bond energy is the amount of energy that is required to separate the chemical bonds between atoms. The study of bond energy...
The pKa of X–H and pKb of Y–Z in a given solvent correlate strongly with the energy of the hydrogen bond formed between them. (C2) Hydrogen bonds are involved in proton-transfer reactions (X–H•••Y → X•••H–Y) and may be considered the partially activated precursors...
In proteins, hydrogen bonds form between the backbone oxygens and amide hydrogens. When the spacing of the amino acid residues participating in a hydrogen bond occurs regularly between positionsiandi+4, an alpha helix is formed. When the spacing is less, between positionsiandi+3, then a 310...
A chemical reaction takes place when chemical bonds break and new bonds form. The reaction can produce energy or require energy to proceed.
such as in water with an oxygen atom and in hydrocarbons with carbon atoms. In the case of water, the covalently bonded hydrogen atoms can form additional intermolecular hydrogen bonds that are weaker than the covalent molecular bonds. These bonds give water some of its physical characteristics. ...
(usual valence of 4). This is because carbon typically bonds with elements which have a similar electronegativity. Examples of covalent bonds formed by carbon include carbon-carbon, carbon-hydrogen, and carbon-oxygen bonds. Examples of compounds containing these bonds include methane, water, and ...
Why is hydrogen important as a future clean energy source? A fuel is a chemical that can be ‘burnt’ to provide useful energy. Burning normally means that chemical bonds between the elements in the fuel are broken and the elements chemically combine with oxygen (often from the air). ...
