Multiple choice Which one of the following is incorrectly matched? [Ag(NH3)2]+ and CO2 - Linear BF3 and CH3+ - Triangular planar NH3 and PCl3 - Pyramidal SF4 and CCl4 - Tetrahedral XeF4 and IF4 - Square planar Reveal answer Fill a bubble to check yourself D Correct answer Explanation This option is correct because the geometry of SF4 is see-saw due to the presence of 4 bond pairs and one lone pair of electrons (according to VSEPR theory, its shape is seesaw), while the geometry of CCl4 is tetrahedral.
