Chemistry - CHEMICAL BONDING Question with Solution | TestHub

The incorrect statement is D. Thermal stability of PCl₅ < PCl₃ because PCl₅ decomposes into PCl₃ and Cl₂ upon heating.

The Lewis base strength order (option A) is correct due to decreasing electronegativity down the halogen group.

Hydrolysis of SbCl₃ (option B) is suppressed by excess HCl due to the common ion effect.

NF₃ (option C) does not undergo hydrolysis due to the absence of d-orbitals and high bond dissociation energy at room temperature.
