Question

Given below are two statements: Statement I: $\text{PF}_5$ and $\text{BrF}_5$ both exhibit $\text{sp}^3\text{d}$ hybridisation.Statement II: Both $\text{SF}_6$ and $[\text{Co}(\text{NH}_3)_6]^{3+}$ exhibit $\text{sp}^3\text{d}^2$ hybridisation. In the light of the above statements,choose the correct answer from the options given below:

• A. Statement I is true but Statement II is false
• B. Both Statement I and Statement II are true
• C. Both Statement I and Statement II are false
• D. Statement I is false but Statement II is true

Answer 1

The Correct Option is C

The hybridisation of the given molecules is as follows:

\(Molecule\)	\(Hybridisation\)
\(\text{PF}_5\)	\(sp^3d\)
\(\text{BrF}_5\)	\(sp^3d^2\)
\(\text{SF}_6\)	\(sp^3d^2\)
\([\text{Co(NH}_3\text{)}_6]^{3+}\)	\(d^2sp^3\)

Thus, both Statement I and Statement II are false.
