Which of the following is not correctly matched?
Which of the following is not correctly matched?
- $PCl_5$ - $sp^3d$ hybridisation
- $PCl_3$ - $sp^3$ hybridisation
- $PCl_{5}$ (solid) - $\left[PtCl_{4}\right]^{+} \left[PtCl_{6}\right]^{-}$
- $PCl_5$ - brownish powder
The Correct Option is C
Solution and Explanation
\(PCl_5\) is yellowish-white powder.
PCl5 is used as a chlorinating reagent. It is a colorless, water-sensitive, and moisture-sensitive solid. In the solid state, PCl5 exists as an ionic solid, [PCl4]+[PCl6]−. The cation, [PCl4]+ is tetrahedral and sp3 hybridized. The anion, [PCl6]− is octahedral and is sp3d2 hybridized.

P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
