It is correct statement that \(NF_3\) is a weaker ligand than \(N(CH_3)_3\), the reason is that fluorine is highly electronegative therefore, it with draw electrons from nitrogen atom. Hence, the lone pair of nitrogen atom cannot be ligated. While \(N(CH_3)_3\) is a strong ligand because \(CH_3\) is electron releasing group.
