If the Assertion is correct but Reason is incorrect.

Vedclass · Answer

(C) $NF_3$ is a weak ligand because the high electronegativity of $F$ atoms withdraws electron density from the $N$ atom,making the lone pair on $N$ less available for donation.In contrast,$N(CH_3)_3$ is a stronger ligand because the $CH_3$ groups are electron-releasing ($+I$ effect),which increases the electron density on the $N$ atom,making the lone pair more available for donation.$NF_3$ is a covalent molecule and does not ionize to give $F^-$ ions in aqueous solution.Therefore,the Assertion is correct,but the Reason is incorrect.

Assertion : $NF_3$ is a weaker ligand than $N(CH_3)_3$.
Reason : $NF_3$ ionizes to give $F^-$ ions in aqueous solution.
