Answer

Brief Explanations:

  1. REDs (Regions of Electron Density):
    • In VSEPR theory, for a molecule with 3 bonding pairs and 1 non - bonding pair (total 4 REDs).
  2. Bonding and Non - bonding:
    • From the structure (3 green atoms bonded to the central red atom), there are 3 bonding REDs.
    • Using the formula (n=\text{bonding pairs}+\text{non - bonding pairs}), if (n = 4) and bonding pairs (= 3), then non - bonding pairs (=1).
  3. Molecular Shape:
    • A molecule with 3 bonding pairs and 1 non - bonding pair of electrons around the central atom has a pyramidal shape.
  4. Bond Angles:
    • For a pyramidal shape (derived from a tetrahedral electron - pair geometry, where the ideal tetrahedral angle is (109.5^{\circ}), but the presence of a lone pair slightly compresses the bond angles, and the approximate bond angle is (109.5^{\circ})).
