  1. Question 1

    Q1. In a methane (CH4) molecule, the four C-H bonds are equivalent and tetrahedral. What is the total sum of all H-C-H bond angles in degrees?

    • A) 438.0
    • B) 657.0
    • C) 328.5
    • D) 109.5

    Answer: 657.0

    Explanation: A tetrahedron has six H-C-H bond angles of 109.5 degrees each, totaling 657 degrees. 438 only accounts for four angles.
