The geometry of water is bent shape because the oxygen atom has the two lone pair and two bond pairs. Ammonia has the trigonal pyramidal shape because it has one lone pair and three bond pairs. The geometry of beryllium chloride is linear because it has the two bond pair only. Geometry of carbondioxide is linear because it has the two bond pair only. Geometry of sulphur tetrafluoride is sea-saw-shape because it has the four bond pair and one lone pair. Geometry of tellurium tetrachloride is sea-saw-shape because it has the four bond pair and one lone pair. Geometry of ${\mathrm{ClF}}_3\&{\mathrm{ICl}}_3$ is T-shape because they have the three bond pair and two lone pairs.

Hence, the incorrect matching amongst the following is ${\mathrm{H}}_2\mathrm{O},{\mathrm{NH}}_3$.
