Answer:
B. two pi bonds and one sigma bond
Step-by-step explanation:
A triple bond is a chemical linkage consisting of three covalent bonds between two atoms of a molecule represented in chemical formulas by three lines or six dotes, as CH ≡ CH or CH ⠿CH.
One sigma bond and two pi bonds make up a triple bond. Pi bonds are created when parallel orbitals are overlapped, whereas sigma bonds are created by the overlapping of hybridized orbitals. There can only be one sigma bond in a chemical bond. Alkynes are compounds that contain triple bonds, the most prevalent of which being one between two carbon atoms. Cyanides and isocyanides are two more functional groups that include a triple bond. Some diatomic molecules, such as dinitrogen and carbon monoxide are also triple bonded. Other than these, some reaction intermediates, like benzyne, contain a triple bond. All types of bonding may be described if orbital hybridization is taken into account. Each carbon atom in acetylene possesses two hybridized sp orbitals and two p orbitals (pure). The x-axis is occupied by the two sp orbitals, which are linear with 180° angles (cartesian coordinate system). On the y-axis and the z-axis, the p-orbitals are perpendicular. The sp orbitals overlap when the carbon atoms get close to one another, creating a sp-sp sigma bond. Additionally, the pz
As orbitals grow close to one another, they create a "pz-pz" pi-bond. The other set of py-orbitals also creates a "py-py" pi-bond. One sigma bond and two pi bonds are created as a consequence.
Although the triple bond can also form via the overlap of three "sp3" lobes without the participation of any pi bonds in a special situation of the bent bond model (the banana bond, where likewise a triple bond is produced).
This is not your typical triple bond in the case of benzyne, which I previously highlighted as a reaction intermediate. The second p contact is the result of a weak sp2 interaction.
hybrid orbitals that are located on the ring's plane.
Because of the limitations imposed by the 6-membered ring, the triple bond is non-linear.
Benzyne is strained and highly reactive.
