Bonding
The type of bonding can be explained in terms of orbital hybridization. In the case of acetylene each carbon atom has two sp orbitals and two p-orbitals. The two sp orbitals are linear with 180° angles and occupy the x-axis (cartesian coordinate system). The p-orbitals are perpendicular on the y-axis and the z-axis. When the carbon atoms approach each other the sp orbitals overlap to form a sp-sp sigma bond. At the same time the pz-orbitals approach and together they form a pz-pz pi-bond. Likewise, the other pair of py-orbitals form a py-py pi-bond. The result is formation of one sigma bond and two pi bonds.
In bent bond theory the triple bond can also formed by the overlapping of three sp3 lobes without the need to invoke a pi-bond.

Famous quotes containing the word bonding:
“The bottom line on bonding with multiples seems to be that if you see bonding as a static event—a moment in time at which you must have eye contact and skin contact simultaneously with two or more infants—you may indeed be in trouble.”
—Pamela Patrick Novotny (20th century)
“Attachment to a baby is a long-term process, not a single, magical moment. The opportunity for bonding at birth may be compared to falling in love—staying in love takes longer and demands more work.”
—T. Berry Brazelton (20th century)
“At the heart of male bonding is this experience of boys in early puberty: they know they must break free from their mothers and the civilized world of women, but they are not ready yet for the world of men, so they are only at home with other boys, equally outcast, equally frightened, and equally involved in posturing what they believe to be manhood.”
—Frank Pittman (20th century)
