Question

The number of lone pairs present on the central atom of ${\mathrm{I}}_3^{-}$ is:

• A. $9$
• B. $1$
• C. $6$
• D. $3$

Answer 1

The correct option is D

$3$

The explanation for the correct option:

D: $3$

Iodine:

• Iodine, denoted by the letter $"\mathrm{I}"$ is a nonmetallic, dark grey or purple-blackish element with atomic number $53$.
• Despite the fact that it may combine with other elements to produce compounds, it is the least reactive and most electropositive halogen.
• On Earth, it is mostly found as the iodide that is water soluble in saltwater and oceans.
• When heated, this element emits a purple hue.
• A few solvents, such as carbon tetrachloride, can dissolve it, however water does not totally dissolve it.
• The element iodine is naturally present in the air, soil, and water. Oceans are the main source of this element.
• Even some minerals include iodine as a component.

Lone pair present in the central atom of ${\mathrm{I}}_3^{-}$ is:

• The structure of the ${\mathrm{I}}_3^{-}$:
• 
• Number of lone pair present in the central atom of ${\mathrm{I}}_3^{-}$ is $3$.

Final Answer: Therefore, Option D is the correct option.
