2-Octyne, also known as methylpentylethyne and oct-2-yne,[1] is a type of alkyne with a triple bond at its second carbon (the '2-' indicates the location of the triple bond in the chain). Its formula is C8H14.[2] Its density at 25 °C and otherwise stable conditions is 0.759 g/ml.[3] The boiling point is 137 °C.[3] The average molar mass is 110.20 g/mol.[2]
It is formed by isomerization of 1-octyne catalyzed by a YbII complex.[4]
