What is the hybridization of P in ##PF_3## and ##PF_5##?

In this answer, I will first teach you a general way to find the hybridization of , And finally I will answer your question.

• To find hybridization ,first draw the Lewis structure.

• Next count the electron regions around the central atom

• Electron regions : Places which are regions of high electron .

  • A triple bond ##rArr## one electron region..
  • A single bond ##rArr## one electron region.
  • An electron lone pair ##rArr## one electron region.

And,

• If there are
• 8 electron regions; hybridization is ##sp^3d^4##.
• 7 electron regions; hybridization is ##sp^3d^3##.
• 6 electron regions; hybridization is ##sp^3d^2##.
• 5 electron regions; hybridization is ##sp^3d##.
  • 4 electron regions; hybridization is ##sp^3##.
  • 3 electron regions; hybridization is ##sp^2##
  • 2 electron regions; hybridization is ##sp##

In

• ##PF_3##==> One lone pair & three single bonds.

In ##PF_3## there are 4 electron regions, so hybridization is ##sp^3##

• In ##PF_5##, there are ##5## electron regions around the central atom (5 single bonds)

• So the hybridization is ##sp^3d##.

I hope this is helpful, what is your feedback?
