Question

In which of the ionic compounds given below there is no octet in the outer shell of either the cation or the anion?​

Answer 1

Explanation:

the octet is in every cell

Answer 2

LiCl and LiH there is no octet in the outer shell of the cation. Here the anion chloride and the Hydrogen ion has filled valance shell but the lithium cation has zero electrons in its valance shell. so it has no octet.

The two elements that most commonly fails to complete an octet are boron and ammonium, they both readily form compounds in which they have six valance electrons, rather than the usual eight predicted by the octet rule.

octet rule : Octet rule states that atoms tend to form compounds in ways that give them eight valance electrons and thus the electron configuration of a noble gas.
