Concept explainers

Alkynes

Alkynes are organic compounds that contain at least one triple bond between carbon-carbon atoms. They are a series of unsaturated compounds with a general molecular formula, CnH2n-2.

Question

Why is the C-C bond length of an alkyne shorter than the C-C bond length of an alkene?
O The orbitals are physically smaller due to mores character.
O Pi bonds are weaker so more pi bonds creates a shorter bond.
O There's a triple bond instead of a double bond.
