Question

Which of the following statement(s) is/are correct?
S1:SeF6 has the octahedral structure and PF5 has sp3d2 hybridization.

Solution

The correct option is D Only S3
S1: The central Se atom has 6 bond pairs of electrons and 0 lone pairs of electrons. It
undergoes sp3d2 hybridisation, which results in octahedral geometry. In case of PF5, the
central P atom has 5 sets of electron pairs (all of which are bonding) and sp3d2 hybridization
corresponds to 6 sets of electron pairs.Therefore PF5 is sp3d hybridized. Hence, statement 1 is
false.
S2:S8(sp3d2) and P4(sp3) both has 25% s- character.
S3: Orbitals in Co+3 ion

[Co(NH3)6]3+


6 pairs of electrons from 6 NH3 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.
