Current Question (ID: 21002)

Question:

$\text{Which of the following species have a trigonal bipyramidal shape?}$ $\text{PF}_5, \text{PBr}_5, [\text{PtCl}_4]^{2-}, \text{SF}_6, \text{BF}_3, \text{BrF}_5, \text{PCl}_5, [\text{Fe(CO)}_5]$

Options:

1. $\text{PF}_5, \text{PBr}_5, \text{PCl}_5, \text{and Fe(CO)}_5 \text{ only}$
2. $\text{BrF}_5, \text{PF}_5, \text{PCl}_5, \text{and PBr}_5 \text{ only}$
3. $\text{PF}_5, \text{PCl}_5, \text{and Fe(CO)}_5 \text{ only}$
4. $[\text{Fe(CO)}_5], \text{BrF}_5, \text{PF}_5, \text{PBr}_5, \text{and PCl}_5 \text{ only}$

Solution:

$\text{Hint: Check molecule having Coordination number five and no lone pair}$ $\text{(1) PF}_5, \text{PCl}_5, \text{PBr}_5, \text{Fe(CO)}_5 \Rightarrow \text{all have trigonal bipyramidal geometry.}$ $\text{(2) BrF}_5 \text{ has a square pyramidal geometry.}$ $\text{(3) [PtCl}_4]^{2-} \text{ has a square planar geometry.}$ $\text{(4) SF}_6 \text{ has an octahedral geometry.}$ $\text{Hence, option 1 is the correct answer.}$
