|Bonding in organic molecules||Sigma Bond – By forming single covalent bonds with four other atoms, a carbon atom can gain the electronic configuration of the noble gas, neon. The single covalent bonds are known as sigma bonds. The shape of the molecule is tetrahedral, and the bond angle is of 109.5Pi Bond – A C=C double bond, as found in alkenes such as ethene, is made up of a sigma bond, and a pi bond. The Pi bond makes a molecule more reactive. The C atoms involved in a double bond are surrounded by three pairs of electrons. The bond angle is of about 120 degrees.|
|Structural Isomerism||Compounds with the same molecular formula but different structural fromulae are called structural isomers.There are three types of structural isomerism:
|Stereoisomerism||Compunds whose molecules have the same atoms bonded to each other but with different arrangements of atoms in space.There are two types of stereoisomerism.
