    attacked. Before we dive into the details of the reaction occurring in scheme 2 it will be important to understand the mechanism which I will provide below: The reason that no base is needed in scheme 2 is due to the two ester groups present in Maleate. Upon the initial attack of PBu3 we see that electrons are pushed onto what was originally one of the double bonded oxygen’s. In the next step‚ the electrons on the oxygen can be pushed down via resonance which causes the carbon-carbon double bond

    Carbon is denoted by the symbol C‚ is part of group 14 on the periodic table‚ and is the fourth most abundant element in the universe (by mass). Carbon has an electron configuration of 1s2‚ 2s2‚ 2p2. With 4 valance shell electrons it is expected to form 4 bonds‚ this means carbon is tetravalent. However the s orbitals do not form the same type of bond (with other atoms) as the p orbitals‚ this is because their shapes are different. For example CH4 would have the following bonds: C(s)-H(s)‚ C(s)-H(s)
