Final answer:
option c,The molecular shape 'Square planar' does not describe any of the given molecules, which are CCl4, CO2, PCl3, PCl5, and SF6.
Step-by-step explanation:
The question asks which description does not apply to any of the listed molecules: CCl4, CO2, PCl3, PCl5, SF6. The options are (A) Linear, (B) Octahedral, (C) Square planar, (D) Tetrahedral, (E) Trigonal pyramidal. By examining each molecule:
- CO2 is linear.
- CCl4 is tetrahedral.
- PCl3 is trigonal pyramidal.
- PCl5 is trigonal bipyramidal (but often approximated to octahedral).
- SF6 is octahedral.
Thus, the only molecular geometry not represented by any of the molecules is (C) Square planar.
CCl4 is carbon tetrachloride and has a tetrahedral shape. CO2 is carbon dioxide and has a linear shape. PCl3 is phosphorus trichloride and has a trigonal pyramidal shape. PCl5 is phosphorus pentachloride and has an octahedral shape. SF6 is sulfur hexafluoride and has an octahedral shape.
Therefore, the molecule that does not describe any of the molecules above is (C) Square planar.
