WebPhenylacetylene is a prototypical terminal acetylene, undergoing many reactions expected of that functional group. It undergoes semi hydrogenation over Lindlar catalyst to give styrene. In the presence of base and copper (II) salts, it undergoes oxidative coupling to give diphenylbutadiyne.

In an ethene molecule, CH 2 =CH 2, the two pairs of electrons which make up the double bond aren't the same. One pair is held securely on the line between the two carbon nuclei in a bond called a sigma bond. The other pair is more loosely held in an orbital above and below the plane of the molecule known as a π bond. scarica app teams microsoft
