Assertion : NF3 is a weaker ligand than N(CH3)3.
Reason : NF3 ionizes to give F– ions in aqueous solution.
- a)If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
- b)If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
- c)If the Assertion is correct but Reason is incorrect.
- d)If both the Assertion and Reason are incorrect.
Correct answer is option 'C'. Can you explain this answer?

It is a correct statement that NF3 is a weaker ligand than N(CH3)3, the reason is that fluorine is highly electronegative therefore, it withdraws electrons from the nitrogen atom. Hence, the lone pair of nitrogen atoms cannot be ligated. While N(CH3)3 is a strong ligand because CH3 has an electron releasing group.

Assertion : NF3 is a weaker ligand than N(CH3)3.
Reason : NF3 ionizes to give F– ions in aqueous solution.
The correct answer to this question is option C, which states that the Assertion is correct but the Reason is incorrect. Let's understand why.
Explanation:
To determine the strength of a ligand, we need to consider its ability to form a coordinate bond with a metal ion. A stronger ligand will have a higher affinity for the metal ion and will form a more stable complex.
Assertion: NF3 is a weaker ligand than N(CH3)3.
This statement is correct. Nitrogen trifluoride (NF3) is a weaker ligand compared to trimethylamine (N(CH3)3). This can be attributed to the electronegativity difference between the central nitrogen atom and the surrounding atoms.
In NF3, the central nitrogen atom is more electronegative than the surrounding fluorine atoms. This leads to a partial negative charge on nitrogen and partial positive charges on fluorine. As a result, the lone pair of electrons on nitrogen is less available for donation to a metal ion, making NF3 a weaker ligand.
On the other hand, in trimethylamine (N(CH3)3), the central nitrogen atom is less electronegative than the surrounding carbon and hydrogen atoms. This results in a partial positive charge on nitrogen and partial negative charges on carbon and hydrogen. The lone pair of electrons on nitrogen is more available for donation to a metal ion, making N(CH3)3 a stronger ligand than NF3.
Reason: NF3 ionizes to give F– ions in aqueous solution.
This statement is incorrect. NF3 does not ionize to give F– ions in aqueous solution. Instead, NF3 behaves as a Lewis base and forms coordinate bonds with transition metal ions.
In aqueous solution, NF3 can act as a ligand and coordinate with metal ions by donating its lone pair of electrons to the metal ion. This coordination results in the formation of a complex compound. However, NF3 does not ionize into F– ions in the process.
Therefore, the Reason provided is not a correct explanation of the Assertion. The correct answer is option C, where the Assertion is correct but the Reason is incorrect.
