Question

Quizplus · Accepted Answer

The H-C-H bond angle in a tetrahedral molecule like CH₄ is approximately 109° due to the tetrahedral geometry of the molecule. Option A (90°) and option D (180°) do not make sense for a tetrahedral molecule. Option C (120°) is a possible bond angle for a trigonal planar molecule, but CH₄ is not trigonal planar. Option E (a and c) is incorrect as 120° is not a valid bond angle for CH₄.
