Symmetrical Alkene

  • A symmetrical alkene is an alkene in whose molecule the doubly bonded carbons bear the same ligands.

    eg. 1:

    In 1, each double bonded carbon bears two methyl groups. Thus, 1 is a symmetrical alkene.

    eg. 2:

    In 2, each doubly bonded carbon bears a methyl group and a hydrogen atom. Thus, 2 is a symmetrical alkene.

    eg. 3:

    In 3, each doubly bonded carbon bears a methyl group and a hydrogen atom. Thus, 3 is asymmetrical alkene.

    In an organic molecule a carbon-carbon double bond in which the carbon atoms bear the same ligands is called a symmetrical double bond.
