QJEEM24Ch6b11: JEE Main 2024 Chemistry - Class 12 JEEM24Ch6b11 Solution: Given below are two statements : Statement I : PF 5 and BrF 5…

Given below are two statements :

Statement I : PF5 and BrF5 both exhibit sp3 d hybridisation.

Statement II : Both SF6 and [Co(NH3)6]3+ exhibit sp3 d2 hybridisation.

In the light of the above statements, choose the correct answer from the options given below :

Multiple Choice Options

  • A Both Statement I and Statement II are false
  • B Statement I is true but Statement II is false
  • C Statement I is false but Statement II is true
  • D Both Statement I and Statement II are true

Step-by-Step Verified Solution

Hybridisation of P in PF5 is sp3d but the hybridisation of Br in BrF5 is sp3d2. So, statement-I is false.

Hybridisation of S in SF6 is sp3d2 but the hybridisation of Co3+ in [Co(NH3)6]3+ is d2sp3 as NH3 is a strong field ligand forcing the unpaired electrons to pair up. So, statement-II is false.
