5 Must Know Facts For Your Next Test

  1. Alkyl groups are classified based on the number of carbon atoms, such as methyl (CH3), ethyl (C2H5), and propyl (C3H7).
  2. They are non-polar and hydrophobic due to their hydrocarbon nature.
  3. Alkyl groups can be primary, secondary, or tertiary depending on the carbon atom's connectivity to other carbons.
  4. They play a crucial role in determining the physical and chemical properties of organic molecules.
  5. Alkyl groups can participate in various reactions, such as substitution and elimination reactions.
