Answer

Brief Explanations:

  • Question 1: Carbon has 4 valence electrons and can form 4 covalent bonds to achieve a stable electron - configuration, allowing for diverse molecular structures.
  • Question 2: Functional groups are specific groups of atoms within molecules that have characteristic chemical behaviors and reactions, determining the overall chemical properties of an organic compound.
  • Question 3: Carbohydrates are made up of monosaccharides (such as glucose), proteins are composed of amino - acids, and nucleic acids are made of nucleotides.

Answer:

  • Question 1: Four
  • Question 2: Functional groups
  • Question 3:
    • Carbohydrate: Monosaccharide
    • Protein: Amino - acid
    • Nucleic Acid: Nucleotide
