Assertion `NF_(3)` is weaker ligands than `N(CH_(3))_(3)`
Reason `NF_(3)` ionises to give `F^(Θ)` ions in aqueous solution .

Options

A. If both `(A)` and ` (R )` are correct and `(R )` is the correct explanation of `(A ) ` .
B. If both `(A)` and ` (R )` are correct and `(R )` is the correct explanation of `(A ) ` .
C. If`(A)` is correct, but `( R )` is incorrect .
D. Both `(A)` and `(R ) ` are incorrect .

Answer

C

Explanation

Correct `(R )` F is highly `EN` it attracts the electrons of `N` towards itself and hence are not easily available on `N` making it a weaker ligand or donor. That is why `NF_(3)` does not ionises to give `F^(Θ)` ions is aqueous solution .
