Physical Properties and Spectroscopy Physically, lower molecular weight alkynes are gases at room temperature, while longer chains exist as liquids or solids. The triple bond can accept two equivalents of electrophile, allowing for the sequential formation of double and single bonds.
Spectroscopic methods, including infrared spectroscopy which detects the characteristic C≡C stretch around 2100-2260 cm⁻¹, are crucial for identifying this functional group in complex mixtures. Terminal alkynes feature the triple bond at the end of the carbon chain, possessing an acidic hydrogen.
