To teach college students the concept of a {pi}-bond, many professors like to use the examples of ethylene and acetylene molecules. Free rotation, restricted rotation, breaking or forming a {pi}-bond are frequently asked questions about the molecules. The cylindrical shape of the {pi} election cloud of acetylene is introduce in most chemistry text books. Some teachers may ask a similar question about the triple bond of acetylene molecule after the question of {open_quotes}Is there a free rotation along the C-C double bond?{close_quotes} being answered {open_quotes}no{close_quotes}. However, the correct answer for the acetylene should be {open_quotes}YES{close_quotes}. The reason for the free rotation about the carbon-carbon triple bond will be discussed experimentally and computationally.
