  1. Question 1

    Q1. In a PCl5 molecule, the axial P-Cl bonds are longer than the equatorial ones. If axial is 240 pm and equatorial is 202 pm, calculate the difference.

    • A) 19
    • B) 38
    • C) 48
    • D) 58

    Answer: 38

    Explanation: The difference between axial (240 pm) and equatorial (202 pm) bonds in PCl5 is 38 pm. 19 is exactly half of the correct difference.
