Triple bond, electronic structure strength

The electronic structure of the triple bond reveals two ir bonds, perpendicular to each other, and a (T bond, formed by two overlapping sp hybrid orbitals. The strength of the triple bond is about 229 kcal mol that of the alkynyl C—H bond is 131 kcal mol . Triple bonds form linear structures with respect to other attached atoms, with short C—C (1.20 A) andC—H( 1.06 A) bonds.
