Jan 07, 2009 · People are often mistaken that ethene contains 2 pi bonds but this is false, in order to have a covalent bond there must be implication of 2 electrons shared between two atoms. However, the double bond between ethene's carbons is composed of 4 shared electrons: 2 as a sigma bond and 2 as a pi bond. The rod has a total charge of -7.50μC.
