  3. Acetyl group - Wikipedia

    en.wikipedia.org/wiki/Acetyl_group

    In IUPAC nomenclature, an acetyl group is called an ethanoyl group. An acetyl group contains a methyl group (−CH 3) that is single-bonded to a carbonyl (C=O), making it an acyl group. The carbonyl center of an acyl radical has one non-bonded electron with which it forms a chemical bond to the remainder (denoted with the letter R) of the molecule.

  4. Chemical bond - Wikipedia

    en.wikipedia.org/wiki/Chemical_bond

    Non-polar covalent bonds in methane (CH 4). The Lewis structure shows electrons shared between C and H atoms. Covalent bonding is a common type of bonding in which two or more atoms share valence electrons more or less equally. The simplest and most common type is a single bond in which two atoms share two electrons.

  5. Covalent bond - Wikipedia

    en.wikipedia.org/wiki/Covalent_bond

    The oxygen molecule, O 2 can also be regarded as having two 3-electron bonds and one 2-electron bond, which accounts for its paramagnetism and its formal bond order of 2. [14] Chlorine dioxide and its heavier analogues bromine dioxide and iodine dioxide also contain three-electron bonds. Molecules with odd-electron bonds are usually highly ...

  6. Non-covalent interaction - Wikipedia

    en.wikipedia.org/wiki/Non-covalent_interaction

    This phenomenon leads to minimum exposed surface area of non-polar molecules to the polar water molecules (typically spherical droplets), and is commonly used in biochemistry to study protein folding and other various biological phenomenon. [22] The effect is also commonly seen when mixing various oils (including cooking oil) and water.

  7. Alkene - Wikipedia

    en.wikipedia.org/wiki/Alkene

    Double bonds are shorter than single bonds with an average bond length of 1.33 Å (133 pm) vs 1.53 Å for a typical C-C single bond. [ 7 ] Each carbon atom of the double bond uses its three sp 2 hybrid orbitals to form sigma bonds to three atoms (the other carbon atom and two hydrogen atoms).

  8. Lone pair - Wikipedia

    en.wikipedia.org/wiki/Lone_pair

    In lead, the effective bond order is reduced even further to a single bond, with two lone pairs for each lead atom (figure C [19]). In the organogermanium compound (Scheme 1 in the reference), the effective bond order is also 1, with complexation of the acidic isonitrile (or isocyanide) C-N groups, based on interaction with germanium's empty 4p ...

  9. Fluorine compounds - Wikipedia

    en.wikipedia.org/wiki/Fluorine_compounds

    The F 2 molecule is commonly described as having exactly one bond (in other words, a bond order of 1) provided by one p electron per atom, as are other halogen X 2 molecules. However, the heavier halogens' p electron orbitals partly mix with those of d orbitals, which results in an increased effective bond order; for example, chlorine has a ...
