Question

The ratio of lone pair and bond pair electrons on central $I$ atom in $I_3^{-}$:

• A. $1$
• B. $1.5$
• C. $0.6$
• D. $0.5$

Answer 1

Answer: (B)

$1.5$

The ratio of lone pair and bond pair electrons on central $I$ atom in $I_3^{-}$ is $1.5$.

Thus, No. of lone pair of electrons $=3$

No. of bond pair of electrons $=2$

The ratio of lone pair and bond pair electrons $=3/2=1.5$
