B)two σ bonds and one π bond.
C)one σ bond and two π bonds.
D)three π bonds.

Question

Quizplus · Accepted Answer

The carbon-carbon triple bond in an alkyne consists of one sigma (σ) bond and two pi (π) bonds. The σ bond is formed by the head-on overlap of sp-hybridized orbitals from each carbon, while the π bonds are formed by the side-to-side overlap of unhybridized p orbitals.
