háromkötéses
háromkötéses refers to a chemical bond characterized by the sharing of three pairs of electrons between two atoms. This type of bond is also known as a triple bond. It is a stronger and shorter bond compared to single or double bonds. Triple bonds are most commonly found between carbon atoms, such as in the alkyne functional group, but can also occur between other non-metal atoms like nitrogen in the N₂ molecule. The formation of a triple bond typically involves the overlap of one sigma bond and two pi bonds. These pi bonds are formed by the lateral overlap of p orbitals. The presence of a triple bond significantly influences the molecule's geometry, rigidity, and reactivity. For instance, molecules with triple bonds often exhibit linear geometry around the bonded atoms. The high electron density in a triple bond makes it a site for addition reactions, where the pi bonds can be broken and new atoms can be added to the carbon chain. The stability of a triple bond is evidenced by its high bond energy.
