  1. Question 1

    Q1. A researcher compares triatomic molecules. Which molecule deviates from a linear shape and adopts an angular geometry due to a lone pair on the central atom?

    • A) SnCl2
    • B) CO2
    • C) BeCl2
    • D) C2H2

    Answer: SnCl2

    Explanation: SnCl2 is V-shaped/angular due to the presence of a lone pair; CO2 is tempting but is perfectly linear with no lone pairs.
