Question

Draw the structural formula of a compound with an unsaturated hydrocarbon with a carbon to carbon triple bond.

Answer 1

• Unsaturated hydrocarbons contain multiple bonds (either double or triple or both).
• As given in the question a minimum of two carbon atoms are necessary to make a Carbon-Carbon Triple ($\mathrm{C}\equiv \mathrm{C}$) bond.
• Let us consider the simplest hydrocarbons containing the Carbon-Carbon Triple ($\mathrm{C}\equiv \mathrm{C}$) bond and that is Ethyne ($C_2{H}_4$).
• The structural formula for Ethyne is as follows

$\underset{\mathrm{Acetyele}\mathrm{or}\mathrm{Ethyne}}{\mathrm{H}-\mathrm{C}\equiv \mathrm{C}-\mathrm{H}}$.
