A triple bond in chemistry is a chemical bond between two atoms involving six bonding electrons instead of the usual two in a covalent single bond. Triple bonds are stronger than the equivalent single bonds or double bonds, with a bond order of three. The most common triple bond is in a nitrogen N 2 molecule; the second most common is that ...
The lowest number possible is given to the triple bond. When no superior functional groups are present, the parent chain must include the triple bond even if it is not the longest possible carbon chain in the molecule. Ethyne is commonly called by its trivial name acetylene. In chemistry, the suffix-yne is used to denote the presence of a ...
Ethynyl group (highlighted red) as part of a large molecule (ethinylestradiol). [1]In chemistry, the suffix-yne is used to denote the presence of a triple bond (≡). [2]The suffix follows IUPAC nomenclature, and is mainly used in organic chemistry.
In fact, the carbon atoms in the single bond need not be of the same hybridization. Carbon atoms can also form double bonds in compounds called alkenes or triple bonds in compounds called alkynes. A double bond is formed with an sp 2-hybridized orbital and a p-orbital that is not involved in the hybridization. A triple bond is formed with an sp ...
In organic chemistry, an addition reaction is an organic reaction in which two or more molecules combine to form a larger molecule called the adduct. [1] [2] An addition reaction is limited to chemical compounds that have multiple bonds. Examples include a molecule with a carbon–carbon double bond (an alkene) or a triple bond (an alkyne).
The central triple bond length is 206 pm, which is around 4% shorter than the typical bond-length of Si–Si double bonds (214 pm)) and the Si–Si single bonds are 237 pm. The colour is attributed to a weak π–π * transition. Calculations show a bond order of 2.6.
The cyanide ion − C≡N is isoelectronic with carbon monoxide − C≡O + and with molecular nitrogen N≡N. A triple bond exists between C and N. A triple bond exists between C and N. The negative charge is concentrated on carbon C. [ 3 ] [ 4 ]
A cycloalkyne consists of a closed ring of carbon atoms containing one or more triple bonds. Cycloalkynes have a general formula C n H 2 n −4 . Because of the linear nature of the C−C≡C−C alkyne unit, cycloalkynes can be highly strained and can only exist when the number of carbon atoms in the ring is great enough to provide the ...
