if two carbon atoms are joined by a triple bond how many other atoms can each carbon atom bond with
When two carbon atoms are joined by a triple bond, they form a molecule called ethyne or acetylene with the chemical formula C2H2.
Each carbon atom in ethyne has three bonds: one sigma bond and two pi bonds. A sigma bond is formed by the overlap of two atomic orbitals, while a pi bond is formed by the overlap of two p-orbitals perpendicular to the axis between the two carbon atoms.
Since each carbon atom has already formed three bonds with each other in the triple bond, they have no remaining unpaired electrons to form additional bonds. Therefore, each carbon atom in ethyne can bond with only one other atom.
