Current Question (ID: 20991)

Question:

$\text{Shape of } \text{OF}_2 \text{ molecule is:}$ $1. \text{ Bent}$ $2. \text{ Linear}$ $3. \text{ Tetrahedral}$ $4. \text{ T-Shaped}$

Options:

1. $\text{Bent}$
2. $\text{Linear}$
3. $\text{Tetrahedral}$
4. $\text{T-Shaped}$

Solution:

$\text{Hint: lone pair-lone pair repulsion in } \text{OF}_2$ $\text{Calculate the steric number for oxygen in } \text{OF}_2 \text{ as follows:}$ $\text{S.N} = \frac{1}{2} \left[ V + M - C + A \right]$ $= \frac{1}{2} \left[ 6 + 2 \right]$ $= 4$ $\text{The hybridization is } \text{sp}^3. \text{ But due to lone pair-lone pair repulsion the shape of } \text{OF}_2 \text{ is bent.}$ $\text{Thus, option 1 is the correct answer.}$
