Question

Assertion (A) $BrF _{5}$ and $SF _{6}$ both have same hybridisation.
Reason (R) $BrF _{5}$ is square pyramidal, while $SF _{6}$ 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 $BrF _{5}$ and $SF _{6}$ both have $s p^{3} d^{2}$ hybridisation but the shape of molecules is different. $BrF _{5}$ is square pyramidal and $SF _{6}$ is octahedral.
It is as follows:

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