Tetrahedral molecular geometry — In a Tetrahedral molecular geometry a central atom is located at the center with four substituents that are located at the corners of a tetrahedron. The bond angles are cos−1(−1/3) ≈ 109.5° when all four substituents are the same, as in CH4. This … Wikipedia
Tetrahedral carbonyl addition compound — A tetrahedral carbonyl addition compound is an organic compound formed by nucleophilic addition to a carbonyl compound such as an aldehyde or ketone. This provides the carbon with four temporary bonds, one of which is broken when the leaving… … Wikipedia
Metallic bond — Metallic bonding is the electrostatic attractive forces between the delocalized electrons, called conduction electrons, gathered in an electron sea , and the positively charged metal ions. Understood as the sharing of free electrons among a… … Wikipedia
Peptide bond — A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, thereby releasing a molecule of water (H2O). This is a dehydration synthesis reaction(also… … Wikipedia
Four-center two-electron bond — A four center two electron bond is a type of chemical bond in which four atoms share two electrons in bonding which is unusual because in ordinary chemical bonds two atoms share two electrons (2c 2e bonding). This type of bonding is postulated in … Wikipedia
Tetrahedrane — is a platonic hydrocarbon with chemical formula carbon4hydrogen4 and a tetrahedral structure. Extreme angle strain (carbon bond angles deviate considerably from the tetrahedral bond angle of 109.5°) prevents this molecule from forming outside of… … Wikipedia
hydrocarbon — hydrocarbonaceous, adj. /huy dreuh kahr beuhn, huy dreuh kahr /, n. any of a class of compounds containing only hydrogen and carbon, as an alkane, methane, CH4, an alkene, ethylene, C2H4, an alkyne, acetylene, C2H2, or an aromatic compound,… … Universalium
Cycloalkane — Ball and stick model of cyclobutane Cycloalkanes (also called naphthenes not to be confused with naphthalene) are types of alkanes that have one or more rings of carbon atoms in the chemical structure of their molecules. Alkanes are types of… … Wikipedia
Cyclol — Figure 1: In the classic cyclol reaction, two peptide groups are linked by a N C’ bond, converting the carbonyl oxygen into a hydroxyl group. Although this reaction occurs in a few cyclic peptides, it is disfavored by free energy, mainly because… … Wikipedia
