Which one of the following molecules has the smallest bond angle?

View answer and explanation

Correct option: D

{\mathrm{H}_2}\mathrm{Se}

Option D (

{\mathrm{H}_2}\mathrm{Se}

) is correct because it has the smallest bond angle due to the increasing size of the central atom down the group, leading to decreased bond pair-bond pair repulsion.
