    Correct Answer(s)
    A. The molecular shape is bent, with an angle of 105 between bonds
    E. The bonds are polar
    H. The molecule is non-symetrical
    I. The molecule is polar
    Explanation
    The correct answer is that the molecular shape is bent, with an angle of 105 between bonds. This means that the molecule has a bent or V-shape structure. The bonds in the molecule are polar, meaning there is an unequal distribution of electron density between the atoms involved in the bond. The molecule is non-symmetrical, as it does not possess any planes of symmetry. Due to the polar bonds and non-symmetrical structure, the molecule is polar, meaning it has a positive and negative end.

This means that the molecule is arranged in a straight line, and the bond angle between the atoms is 180 degrees. Additionally, the answer states that the bonds are polar, indicating that there is an uneven distribution of electron density in the bonds. However, it also states that the molecule is symmetrical, which means that the arrangement of atoms is balanced and there is no net dipole moment. Therefore, the molecule is non-polar.

      The molecule is non-symetrical

    • I.

      The molecule is polar

    • J.

      The molecule is non-polar

    Correct Answer(s)
    C. The molecular shape is trigonal planar with an angle of 120
    E. The bonds are polar
    G. The molecule is symetrical
    J. The molecule is non-polar
    Explanation
    The correct answer is that the molecular shape is trigonal planar with an angle of 120, the bonds are polar, the molecule is symmetrical, and the molecule is non-polar. This is because in a trigonal planar shape, the central atom is surrounded by three bonded atoms and there are no lone pairs of electrons. The bond angle in a trigonal planar shape is 120 degrees. The bonds are polar because there is a difference in electronegativity between the atoms involved in the bonds. However, the molecule is symmetrical, which means that the polar bonds cancel out each other's effects, resulting in a non-polar molecule.

    C. The molecular shape is trigonal planar with an angle of 120
    E. The bonds are polar
    G. The molecule is symetrical
    J. The molecule is non-polar
    Explanation
    The correct answer is that the molecular shape is trigonal planar with an angle of 120 degrees. This means that the molecule has three atoms bonded to the central atom in a flat, triangular shape. The bonds are polar, indicating that there is an uneven distribution of electron density between the atoms involved in the bond. However, despite the polar bonds, the molecule is symmetrical, resulting in a cancellation of the polarities and making the overall molecule non-polar.

    D. The molecular shape is tetrahedral with an angle of 109.5
    E. The bonds are polar
    G. The molecule is symetrical
    J. The molecule is non-polar
    Explanation
    The correct answer is the molecular shape is tetrahedral with an angle of 109.5, the bonds are polar, the molecule is symmetrical, and the molecule is non-polar. The tetrahedral shape is determined by the presence of four bonded atoms around the central atom. The bond angle of 109.5 is characteristic of a tetrahedral shape. The bonds are polar because there is a difference in electronegativity between the atoms involved in the bond. However, the molecule is symmetrical, which cancels out the polarity and makes the molecule overall non-polar.
