Which of the following statement is false?
Options
- APermanent magnetic moment of [ C u N H 3 ) 4 2 + is 1.732 B.M.
- BEquilibrium constant is the ratio of rate constants of forward and backward reactions
- C[ N i C O ) 4 is tetrahedral
- DFor forming N C l 5 'N' adopts s p 3 d hybrid state
Correct answer
D. For forming N C l 5 'N' adopts s p 3 d hybrid state
Step-by-step solution
As vacant d-orbitals are not available in nitrogen hence it can not exhibit a valency of 5 i.e. N C l 5 is not possible. Rest other statements are correct here. K e q = K f K b [ N i C O ) 4 is tetrahedral as Ni is having s p 3 hybridisation. Permanent magnetic moment of [ C u N H 3 ) 4 2 + is 1.732 B.M as in it C u 2 + has 1 unpaired electron so μ = n n + 2 = 1 1 + 2 = 1.73 BM
