  • What is optical isomerism a form of?
    Stereoisomerism
  • What do optical isomers have in common?
    They have the same structural formula
  • How do optical isomers differ from each other?
    They have different arrangements of atoms in space
  • What is a chiral carbon atom?
    A carbon atom with four different groups attached
  • What is a classic example of a chiral center?
    Human hands
  • What are enantiomers?
    Optical isomers that are mirror images of each other
  • What does non-superimposable mean in the context of optical isomers?
    They cannot be placed on top of each other to match perfectly
  • How can you visually demonstrate that two hands are non-superimposable?
    By trying to overlap them without complete matching
  • What is the first step in identifying a chiral center in a molecule?
    Find the carbon atom with four different groups surrounding it
  • What is the tetrahedral shape associated with in chemistry?
    The arrangement of groups around a chiral carbon
  • How do you represent enantiomers in a diagram?
    By drawing a mirror line between them
  • What is plane polarized light?
    Light that oscillates in only one direction
  • How do optically active isomers affect plane polarized light?
    They rotate the plane of polarized light
  • What is the relationship between the rotation of plane polarized light and enantiomers?
    One enantiomer rotates it clockwise, the other counterclockwise
  • What type of amino acids are mostly found in nature?
    L amino acids
  • What is ascorbic acid commonly known as?
    Vitamin C
  • What functional group do aldehydes and ketones contain?
    A carbonyl functional group
  • Where is the carbonyl group located in aldehydes?
    At the end carbon of the molecule
  • How do you name an aldehyde?
    By ending the name with "al"
  • How do you name a ketone?
    By ending the name with "one"
  • What is the difference in the position of the carbonyl group between aldehydes and ketones?
    Aldehydes have it at the end, ketones have it in the middle
  • What functional group do aldehydes and ketones contain?
    Carbonyl functional group
  • What is the main difference between aldehydes and ketones?
    The position of the carbonyl group

  • What defines a diol?
    A molecule with two hydroxyl groups
  • How are diols named?
    By counting the carbons and assigning numbers to the hydroxyl groups
