Question

A valid Lewis structure cannot be drawn for which of the following compounds?

• A. $N{F}_3$
• B. $C{H}_4$
• C. $IC{l}_5$
• D. $Si{F}_4$

Answer 1

The correct option is C $IC{l}_5$

$\left(a\right)$ The central atom has 8 valence electrons.


$\left(b\right)$ The central atom has 8 valence electrons.

$\left(c\right)$ The central atom has 12 valence electrons.

$\left(d\right)$ The central atom has 8 valence electrons.

Since $IC{l}_5$ has an expanded octet, it violates the octet rule.
