The simplest alkyne, ethyne (also known as acetylene), has two carbon atoms and the molecular formula of C 2 H 2. The structural formula for ethyne is The structural formula for ethyne is In longer alkyne chains, the additional carbon atoms are attached to each other by single covalent bonds.

compound,called,the,condensed,structural,formula?, The structural formula shows all the bonds, including the bonds between the carbon and hydrogen atoms, while the condensed structural formula only shows the bonds between the carbon atoms. The condensed formula is shorter to write. 2. May 01, 2008 · Best Answer: 2-Butyne a hydrocarbon that has four carbon atoms and one triple bond between the two middle carbons. The condensed formula is: CH3CCCH3. 1-Butyne as above but has its triple bond between two end carbons: The gas ethane, for example, has the molecular formula C 2 H 6. The simplest structural formula, drawn either in a condensed or in an expanded version, reveals that ethane consists of two carbon atoms bonded to one another, each carbon atom bearing three hydrogen atoms. Such a two-dimensional representation…
