WebOct 26, 2024 · Alkenes are unsaturated hydrocarbons with at least one double bond between carbon atoms. Aromatic hydrocarbons are unsaturated cyclic hydrocarbons with alternating single and double bonds between carbon atoms. Alkynes are unsaturated hydrocarbons with at least one triple bond between carbon atoms. In acetylene, the H–C≡C bond angles are 180°. By virtue of this bond angle, alkynes are rod-like. Correspondingly, cyclic alkynes are rare. Benzyne cannot be isolated. The C≡C bond distance of 121 picometers is much shorter than the C=C distance in alkenes (134 pm) or the C–C bond in alkanes (153 pm).
