Isomers

• Isomerism is the occurrence of compounds with identical molecular formula but different structures.
• The two types of isomers are structural isomers and stereoisomers.
• Structural isomers have the same molecular formula but the atoms are arranged in a different sequence.
• Type of isomers that differ in spatial arrangements around a double bond or ring structure but have the same covalent bond.

  Geometric isomers
• Two types of sterioisomers are geometric isomers and enantiomers.
• Enantiomers are also known as...

  Optical isomers
• What are isomers?

  Different compounds with the same molecular formula.
• The type of isomers that are mirror images of each other are called enantiomers.
• Which functional group is R-CH3?
