Question

answer this.....!!!!!!!

Answer 1

the option "a" is the answer to your question. the cause of them is diagonal relationship. this also occurs as the Li atom is very small in size. so this shows many exceptional properties. the answer to your question is also one type of exceptional property sho2n by Li atom and it's ions

Answer 2

solution:

▶Here, we know that stability is directly proportional to the bond order of elements.

Thus, Bond order of;

Li2 = 1

Li2 + = 0

Li2 - = 0

Thus, here we can say that Li2 is more stable than others..

▶Now, we have to check anti bonding electron (Lone pair electrons)

As, less lone pair electron more stability

▶L.p ∝ 1/stability

Thus, Li2 + have 2 anti bonding electrons and Li2- have 3 lone pair.

Thus, overall order of stability is
Li 2 > Li 2+ > Li 2-

Hence, option (c) is correct

Still any doubt in calculating Lone pair Or Bond order ?
