    • 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
