Multiple choice The molecule having the smallest bond angle is __________. AlCl3 CH4 H2O H2S XeF4 Reveal answer Fill a bubble to check yourself E Correct answer Explanation XeF4 has square planar geometry with bond angle 90o. It has the least bond angle among the given molecules. Increasing order of bond angle: XeF4 (90o) < H2S (92.3o) < H2O (104.5o) < CH4 (109.5o) < AlCl3 (120o)
