    1. What is the molecular shape of BI3?

    • Tetrahedral

    • Trigonal pyramidal

    • Linear

    • Trigonal planar

    • Octahedral

    Correct Answer
    A. Trigonal planar
    Explanation
    The correct answer is trigonal planar. In the molecule BI3, there are three bonding pairs of electrons and no lone pairs on the central atom. This arrangement gives rise to a trigonal planar molecular shape, where the three bonding pairs are spread out in a flat triangle around the central atom. The bond angles in a trigonal planar molecule are approximately 120 degrees.

    3. What is the molecular shape of C2H2?

    • Tetrahedral

    • Trigonal pyramidal

    • Linear

    • Trigonal planar

    • Octahedral

    Correct Answer
    A. Linear
    Explanation
    The molecular shape of C2H2 is linear because it consists of two carbon atoms bonded together with a triple bond. The triple bond consists of one sigma bond and two pi bonds, which results in a linear arrangement of the atoms.

    5. What are the bond angles of SCl6?

    • 180 deg

    • 90 deg/ 120 deg

    • 109.5 deg

    • 90 deg

    • 120 deg

    Correct Answer
    A. 90 deg
    Explanation
    The correct answer is 90 deg. This is because SCl6 has an octahedral molecular geometry, meaning it has six bonding pairs and no lone pairs of electrons around the central sulfur atom. In an octahedral geometry, the bond angles between the bonding pairs are all equal and measure 90 degrees.

    2. What is the electron geometry of NF3?

    • Tetrahedral

    • Trigonal pyramidal

    • Linear

    • Trigonal planar

    • Octahedral

    Correct Answer
    A. Tetrahedral
    Explanation
    The electron geometry of NF3 is tetrahedral. This means that the central nitrogen atom is surrounded by four electron pairs, including three bonding pairs and one lone pair. The presence of the lone pair causes the molecule to have a trigonal pyramidal molecular geometry.
