Question

Which of the following statement(s) is/are correct?
$$S_1: SeF_6$$ has the octahedral structure and $$PF_5$$ has $$sp^3d^2$$ hybridization.
$$S_2$$: The percentage of s-character in the orbital forming S−S bonds and P−P bonds in $$S_8$$ and $$P_4$$ molecules respectively are 25% and 33.3%.
$$S_3:$$ $$[Co(NH_{3})_{6}]^{3+}$$ is an inner orbital complex as well as diamagnetic in behaviour.

Solution

The correct option is D Only $$S_3$$
$$S_1:$$ The central Se atom has 6 bond pairs of electrons and 0 lone pairs of electrons. It
undergoes $$sp^3d^2$$ hybridisation, which results in octahedral geometry. In case of $$PF_5$$, the
central P atom has 5 sets of electron pairs (all of which are bonding) and $$sp^3d^2$$ hybridization
corresponds to 6 sets of electron pairs.Therefore $$PF_5$$ is $$sp^3d$$ hybridized. Hence, statement 1 is
false.
$$S_2: S_8(sp^3d^2)$$ and $$P_4(sp^3)$$ both has $$25\%$$ s- character.
$$S_3:$$ Orbitals in $$Co^{+3}$$ ion
$$\boxed {\uparrow \downarrow} \boxed {\uparrow} \boxed {\uparrow}\boxed {\uparrow}\boxed{\uparrow}$$ $$ \boxed { }$$ $$\boxed { } \boxed { } \boxed { }$$
$$3d$$ $$4s$$ $$4p$$

$$d^2sp^3$$

$$[Co(NH_3)_6]^{3+}$$
$$\boxed {\uparrow \downarrow} \boxed {\uparrow \downarrow} \boxed {\uparrow\downarrow}$$ 
$$\boxed {\uparrow \downarrow}\boxed {\uparrow \downarrow}\boxed {\uparrow\downarrow}\boxed {\uparrow \downarrow}\boxed {\uparrow \downarrow}\boxed {\uparrow\downarrow}$$
$$6$$ pairs of electrons from $$6 \ NH_3$$ molecules.
Inner '$$d$$' orbitals are used in hybridization so its inner orbital complex. There are no
unpaired electrons so that it is diamagnetic.
Option D is correct.
