The shapes of \(\mathrm{BrF}_5\) and \(\mathrm{XeF}_4\), respectively are
- A square pyramid, square pyramid
- B square planar, square planar
- C square planar, square pyramid
- D square pyramid, square planar
Answer & Solution
Correct Answer
(D) square pyramid, square planar
Step-by-step Solution
Detailed explanation
In \(\mathrm{BrF}_5\), order to obtain pentavalency, some of electrons are shifted to \(4 d\)-orbitals. Two of \(p\)-orbitals become unpaired. During hybridisation one \(4 s\), three \(4 p\) and two \(4 d\) orbitals take part. Therefore, hybridisation is \(s p^3 d^2\). In…
