Question

Assertion (A) $Br{F}_5$ and $S{F}_6$ both have same hybridisation.
Reason (R) $Br{F}_5$ is square pyramidal, while $S{F}_6$ molecule is octahedral.

• A. Both $A$ and $R$ are correct; $R$ is the correct explanation of $A$.
• B. Both $A$ and $R$ are correct; $R$ is not the correct explanation of $A$.
• C. $A$ is correct; $R$ is incorrect.
• D. $A$ is incorrect; $R$ is correct.

Answer 1

Answer: (B)

Both $Br{F}_5$ and $S{F}_6$ both have $s{p}^3{d}^2$ hybridisation but the shape of molecules is different. $Br{F}_5$ is square pyramidal and $S{F}_6$ is octahedral.
It is as follows:

Thus, both $A$ and $R$ are correct; $R$ is not the correct explanation of $A$.
