Vedclass · Answer

(A) True: Hybrid orbitals have more directional character and overlap more effectively,forming stronger bonds than pure atomic orbitals.$(b)$ False: Canonical structures (resonance structures) differ only in the arrangement of electrons,not in the arrangement of atoms.$(c)$ False: $A$ symmetrical molecule like $PCl_5$ (trigonal bipyramidal) is symmetrical but contains different bond angles $(180^{\circ}, 120^{\circ}, 90^{\circ})$.$(d)$ True: $VSEPR$ theory accounts for the lone pairs on $Xe$ in $XeF_4$,predicting its square planar geometry.

Column-$I$	Column-$II$
$(P)$ $\underline PCl_5 \to PCl_3 + Cl_2$	$(i)$ Change in hybridisation
$(Q)$ $\underline SO_3 \to \underline SO_2 + \frac{1}{2}O_2$	$(ii)$ Change in bond angle
$(R)$ $\underline NH_3 + H^{+} \to \underline NH_4^+$	$(iii)$ Change in shape
$(S)$ $H_2\underline O + H^{+} \to H_3\underline O^{+}$	$(iv)$ Change in oxidation state
