Question

Which statement is correct? Group of answer choices none of these H2O is linear. The bonds in LiF have a more covalent character than those in F2. The diatomic molecule Cl2 is an example of a polar molecule. The molecule ClO2 cannot be accurately described by a Lewis structure consistent with the octet rule.

Answer 1

Answer: The statement molecule $ClO_{2}$ cannot be accurately described by a Lewis structure consistent with the octet rule, is true.

Explanation:

As the chemical formula of water is $H_{2}O$ and since it contains electronegative oxygen atom which also has 2 lone pair of electrons. Hence, lone pair-bond pair repulsion occurs due to which water has a bent shape structure.

The compound LiF contains metal lithium and non-metal fluorine. In order to obtain stability lithium donates its valence electron to the fluorine atom leading to the formation of an ionic bond. Hence, LiF is an ionic compound and not a covalent compound.

Generally, ionic compounds are polar in nature. For example, KOH is a polar compound and $Cl_{2}$ is a non-polar compound.

Thus, we can conclude that the statement molecule $ClO_{2}$ cannot be accurately described by a Lewis structure consistent with the octet rule, is true.
