Current Question (ID: 8053)

Question:

$\text{Which of the following pairs of species have similar shapes?}$

Options:

1. $\text{PCl}_3, \text{NH}_3$
2. $\text{CF}_4, \text{SF}_4$
3. $\text{PbCl}_2, \text{CO}_2$
4. $\text{PF}_5, \text{IF}_5$

Solution:

$\text{HINT: Compound having same hybridization has same shape.}$ $\text{Explanation:}$ $\text{STEP 1:}$ $\text{Molecules} \quad \text{Hybridisation} \quad \text{Shape}$ $\text{PCl}_3 \quad sp^3 \quad \text{Trigonal Pyramidal}$ $\text{NH}_3 \quad sp^3 \quad \text{Trigonal Pyramidal}$ $\text{CF}_4 \quad sp^3 \quad \text{Tetrahedral}$ $\text{SF}_4 \quad sp^3d \quad \text{See-saw}$ $\text{PbCl}_2 \quad sp^2 \quad \text{Bent}$ $\text{CO}_2 \quad sp^2 \quad \text{Linear}$ $\text{PF}_5 \quad sp^3d \quad \text{Trigonal Bipyramidal}$ $\text{IF}_5 \quad sp^3d^2 \quad \text{Square Pyramidal}$ $\text{STEP 2:}$ $\text{PCl}_3 \text{ and } \text{NH}_3, \text{ both have same hybridization that is } sp^3. \text{ Therefore, both have same shape.}$ $\text{Both have pyramidal structure.}$
