Questions and Answers

What is a substrate in organic reactions?

  • A molecule that initiates the reaction
  • A short-lived species formed during the reaction
  • A substance that stabilizes the product
  • A molecule that can be attacked (correct)

    • What occurs during heterolysis?

  • The bond breaks without forming intermediates
  • Each atom receives one electron from the bond
  • Both electrons remain with the original atom
  • One electron goes to each atom (correct)

    • Why are intermediate species considered unstable?

  • They are permanent states in the reaction
  • They have a high energy state and can rearrange electronically (correct)
  • They lack any electron configurations
  • They form strong ionic bonds

    Substrate

    A molecule that is attacked by a reagent in a chemical reaction.

    Reagent

    A substance that attacks the substrate in a chemical reaction.

    Intermediate

    A short-lived species formed during a chemical reaction. Often unstable and undergoes rearrangements to gain stability.

    Heterolysis

    A bond breaking process where one electron from the bond goes to each atom. This forms ions.
