Which formula represents an alkyne?

Which formula represents an alkyne?

(1) CnHn

(2) CnH2n + 2

(3) C2nHn

(4) CnH2n – 2

Alkynes are a group of organic molecules that have a triple bond. The formula for alkynes is CnH2n-2, making choice 4 the correct choice. The formula for alkanes (all single bonds) is CnH2n+2, and that for alkenes (molecules that have a double bond) is CnH2n. Alkenes as well as alkynes are unsaturated hydrocarbons, while alkanes are saturated hydrocarbons.
