Statement I: NF3 is a weaker ligand than N(CH3)3
Statement II: NF3 ionizes to give F- ions in aqueous solution
To determine the correctness of the statements and the relationship between them, let's analyze each statement individually and then evaluate their correlation.
Statement I: NF3 is a weaker ligand than N(CH3)3
NF3 and N(CH3)3 are both ligands, which are molecules or ions that can donate a pair of electrons to a central metal atom or ion to form a coordinate bond. The strength of a ligand is determined by its ability to donate electrons and form a stable bond with the central metal atom or ion. In general, electron-donating groups increase the stability of the bond, making the ligand stronger.
NF3 is a weaker ligand than N(CH3)3 because the electronegativity of nitrogen in NF3 is higher than that in N(CH3)3. The presence of electronegative fluorine atoms in NF3 leads to a stronger electron-withdrawing effect, reducing the electron-donating ability of the nitrogen atom. On the other hand, the methyl groups in N(CH3)3 have a weaker electron-withdrawing effect, allowing the nitrogen atom to donate electrons more readily.
Statement II: NF3 ionizes to give F- ions in aqueous solution
Ionization refers to the process of forming ions by losing or gaining electrons. In the case of NF3, it can undergo partial ionization in aqueous solution, resulting in the formation of F- ions. This ionization process occurs due to the polar nature of the NF3 molecule and its ability to interact with water molecules. The electronegative fluorine atoms in NF3 attract the partially positive hydrogen atoms in water, leading to the formation of hydrogen bonds. This interaction can result in the dissociation of NF3 into F- ions and H+ ions.
Evaluation of the statements:
Both Statement I and Statement II are correct. NF3 is a weaker ligand than N(CH3)3 due to the electron-withdrawing effect of the fluorine atoms. Additionally, NF3 can ionize in aqueous solution to give F- ions due to its ability to form hydrogen bonds with water molecules.
Relationship between the statements:
Statement II provides a correct explanation for Statement I. The electron-withdrawing effect of the fluorine atoms in NF3 reduces its ability to donate electrons, making it a weaker ligand compared to N(CH3)3. The ionization of NF3 in aqueous solution further supports its weaker ligand behavior.
Therefore, the correct answer is option B: Both Statement I and Statement II are correct, but Statement II is not the correct explanation of Statement I.
